How many hours of light is required for long and short day lighting?
- The amount of lighting varies by plant type. However, a general rule would be more than 12 hours of darkness for short-day plants, less than 12 hours of darkness for long-day.

Answer . it depends,the flourecent kind hols 60 watts,lumens has 120 and they last for 10,000 hours.
A light year, the measure of the distance light travels in one year, is actually a measure of distance and not a measure of time....
A light year is a measure of distance, not time. A light year is the distance light travels in one year. In one day light travels 16,081,407,123 miles.
The length of the day varies depending depending on latitude and season (Winter, Fall, etc.)
it varies but we get about 8 hours daylight in winter extending to about 16 hours in summer
There usually isn't. The amount of sunlight varies from place to place and season to season. The average is half and half.. It is hard to explain, but the whole concept of time is a man made concept. He looks at nature and related it to what he saw. The Earth goes through a cycle of time, a revolut…ion around the axis is a day. ( Full Answer )
The two units are not convertible. Day is a unit of time. A light-year isn't a measure of time, it's a measure of distance. It's equal to the distance that light travels in one year. Light takes time to travel from one location to another. When you turn on a flashlight and shine it at an object, …it may seem that the object is illuminated instantly, with no time passing, but there actually is a small amount of time between the time that you turn on the switch until the light hits the object then about the same amount of time for the light to reflect back to your eye and only then will you 'see' the object. Just like if you are talking to somebody in a room, the sound appears to pretty much instantly travel from the person's mouth to your ears, but if you are in a canyon, you can yell then maybe a second later hear your echo. Light works the same way, but on a much faster scale. With light traveling at approximately 186,000 miles per second (sound travels only about 0.2 miles per second, by comparison), multiplied by how many seconds in a year, one light year equals 5.8785 e+12 miles. To help put this in perspective, if the sun "burned out", we wouldn't know it for eight minutes. Try to visualize how far that could travel in a whole year! Similarly, a light minute is the distance that light travels in one minute. For example, Earth is 8 light minutes distant from the Sun. (93,000,000 miles) While all of this may seem too 'large scale' to be pertinent, the fact that light has a constant speed, is useful to the development to some devices which you may experience or take advantage of. . RADAR sends a beam of electromagnetic waves (not visible light, but it travels at the speed of light), which then bounces off of an object and reflects back. The RADAR unit measures the amount of time it took to reflect back, then using the known speed of light, can calculate how far away the object is. . GPS devices take advantage of the fact that the radio signals (again traveling at the same constant speed of light) will reach your device at different times, depending on how far away the satellite is from you. The satellites 'know' where they are, and with enough signals received, the computer program inside your GPS device can calculate it's own position. ( Full Answer )
\n365 days a year (every day). Except in Lapland (northern finland) where there is no sunlight a few weeks a year.
The answer depends upon how far north (or south) you are. During the winter solstice at the north pole (or anywhere above the arctic circle), there is no sunlight whatsoever. The further south you go, the longer the sun peeps up above the southern horizon at noon.
well more then 300 kk its is easy go on the website, www.how many hours of light are there in a day on Saturn
the earth has light every day except in Alaska it has 205 days every year now if you talkin about how many days the earth has light left we in all facts we have about 100 million years left
The 'light year' is the distance that light travels in a year's time.. Since it's a unit of distance and not a unit of time, it can't be converted into a number of days, any more than you can tell me how many inches old you are.
Watt-hour a light bulb consumes 3600 watt-hours per day How many watt-hours does it consume in 4 days and 6 hours?
A light bulb consumes watt-hours per day. How many watt-hours does it consume in days and hours?
Light hours are not a unit of time, they are a unit of distance. 2.4 light hours is how much distance light can travel in 2.4 hours. As the velocity of light is 300 billion meters a second, it's about 2.6 billion km.
The hours of day light ranges from 8 hours (midwinter) to 16 hours (midsummer) in vienna.
it just depends on where you live and the season. in the intior of Alaska in the winter, around Xmas, there is only a couple of hours. in the summer it is almost always sunny
On Earth, it's daylight and cold all day for part of the year near the North and South poles.Just inside the Arctic circle it's daylight all day for a week or two, but it isn't usually cold.
This was my question too! But the internet is full of off topic questions! Im getting angry....
For any specific place on Earth, it depends on the season and latitude. Locations on the equator receive 12 hours of daylight per day, consistently. The poles on the other hand have weeks with no sunlight at all (in winter) and weeks with no night (in summer).
depends on where u live, equator has 12 hours of light, but the true is that generally the same amount of time.
Antarctica starts to gets 24 hours of daylight between the Vernal equinox and the Autumn equinox. The days gradually lengthen until summertime. However, this does not mean continuous sunlight. That only happens during the southern hemisphere summer months when, for a period of time, the sun never ac…tually sets below the horizon, but seems to circle around in the sky. ( Full Answer )
A light bulb consumes 19800 watt-hours in 5 days and 12 hours How many watt-hours does it consume per day?
5 days 12 hours = 5.5 days 19,800 / 5.5 = 3,600 watt-hours per day = 150 watts
A light bulb consumes 7800 watt-hours in 3 days and 6 hours How many watt-hours does it consume per day?
7800 watt-hours. 3 days 6 hours. 3 days x 24 hours in a day = 72 hours 72 hours + 6 hours = 78 hours. 7800 watt-hours / 78 hours = 100 watts/hour 100 watts/hour x 24 hours = 2400 watts/day just did that fast, might be wrong? :P
The tropical day is near to 12 hours as is the night. The nearer the equator, the closer it is to 12 hours per day and 12 hours per night.
At the north and south poles . . . all the time Everywhere else . . . on the occasion of the equinoxes, March 21 and September 21.
If you stood at one spot on the moon, you would see the sun up for 14.8 days , and down for the next 14.8 days. (However, even with the sun up in your sky, you would still see the stars.) Another interesting thing to think about: If you stood anywhere on about 1/2 of the moon's surface, t…he earth would always be up in your sky. If you stood anywhere on the other 1/2 of the moon's surface, the earth would never be up in your sky. ( Full Answer )
It is hard to know, but most likely hiding in trees and bushes, half-sleeping, making sure it can get away if it gets into danger.
1 light-hour = 7.2 AU (rounded) 1 light-hour is approximately 1.08Ã10 9 km, while 1 AU is approximately 1.5 x 10 8 km (149,597,870,700 m).
A full rotation of Pluto takes 6 Earth days, 9 hours, and some minutes; so the day part should be about half that amount (3 days and 5 hours), at least on average. Pluto has a very large tilt of its axis, similar to Uranus. So the details of when it's daylight on Pluto are complicated and depend o…n where Pluto is in its orbit around the Sun. Of course, Pluto is so far from the Sun that the term "daylight" is a bit misleading anyway. ( Full Answer )
The summer solstice has the longest daylight hours. It occurs on July 21 or 22.
It depends on your latitude, i.e., how far north or south of the equator you live. If you are sufficiently far north (or south), it can be up to 24 hours.
Like many other things, that will depend on your precise location; the number of daylight hours in Presque Isle, Maine will be longer than the number of daylight hours in Newport, Rhode Island. Here is the sunrise/sunset data for Presque Isle, ME on June 21, 2010: Sunrise 4:38 a.m. Sunset 8:…29 p.m. Twilight at this latitude adds about a half-hour at either end of the day. So, it looks like about 15.8 hours. It would be somewhat less south of Presque Isle, and a little longer anywhere north of there. ( Full Answer )
A light-year is a unit of distance. It is not a unit of time. 365 light days, unless it is a light leap year.
This is an impossible conversion to make. A hour is a unit of time.A light year is a unit of distance, specifically, it is thedistance light travels in a year.
The average life span of a light bulb being on 8 hours a day is 2000 hours.
Habaneros and other nightshades (tomatoes, peppers, eggplants, and potatoes) are sun- and- heat-loving plants that need a minimum of 5-6 hours of strong sun per day to flower and set fruit. 8-10 hours is even better.
On average throughout the year, 12. But it varies GREATLY with the date and with the location. The time of sunrise and sunset is very dependent on the date and exact location. A difference of 15 miles can change the time of sunrise or sunset by a minute. Please re-post your question with a city name… or zip code. You can easily calculate the time of sunrise or sunset by visiting the web site of the U.S. Naval Observatory at the related link called Naval Observatory. ( Full Answer )
this depends where in the united states you are and when you are in the united states; by when i mean what month. This depends on where the sun is compared to your locations as for the autumnal and spring equinox it is 12 hours. (equal = equinox) and for the winter and summer solstice it is either a…bout 8 hours or about 15 hours. sorry for my grammer i am only in 8th grade ( Full Answer )
you tell me. OK. Day light hours change due to the changes in the eccentricity and inclination of the Earth's orbit. We good?
Speed of light c = 299792458 m/s Ã 1 km/1000 m = 299792.458 km/s. Speed of light c = 299792.458 km/s Ã 3600 s/ 1 hr = 1079252848.8 km/hr.
At the north and south poles it is possible to get days which are completely light, and also days which never see any sunlight.
It depends where you are on the planet. In the Northern hemisphere, just two days are of equal length during the year - they are the spring & autumn equinox. However - if you're stood on the equator, every day will have the same length !
At the north pole, the longest day of the year is six months long. The sun is up continuously, in the sky, above the horizon, and does not set for 6 months. And June 21 is the day right in the middle of that period.
Light-hours is a measure of distance, not time. It is the distance light travels in a vacuum in one hour's time. In this case, 13 light-hours equates to 8,718,016,181 miles.
A light year is around 10 trillion km. A light second is 300,000 km A hour has 3600 seconds The answer is 1,080,000,000 km Something you might want to know is the distance from the sun to the Earth is around 8 light minutes.
Now, as for sunlight, that depends on latitude. The higher thelatitude, the further north and south, the longer the day insummer, and the shorter the night. Above the arctic and antarcticcircles, the sun does not set for at least 1 night in summer anddoes not rise for at least 1 day in winter. As yo…u continue furthernorth and south toward the poles, the number of nights in summerwithout sunset and the number of days in winter without sunriseincreases. It does not go completely black as for an hour or sobefore and after sunrise and sunset, there is still light in thesky, twilight, so even if there is no sunrise, the day DOESbrighten until the local noon and is darkest at local midnight.... ( Full Answer )
At both poles, beyond about 66 degrees, the geography experiencesat least one 24-hour period of no sunrise/ sunset per year. Depending on where you are on the continent, this period can be upto six months. When the sun comes up, it stays up 24/7, until it sets.
Not all days has the same sunlight. Canada's more densely populated areas get approximately2,000 hours of bright sunshine annually. If you visit here, youcould use the chart. Vancouver, Canada - Sunrise, sunset, moontimes for today
Its average distance is 30 astronomical units so the time taken is30 times 8 minutes, which is 4 hours.
That depends on where on the planet you live. If it is the shortest day in your hemisphere, then you could have anything from 0 hours, if you are at the pole to 12 hours if you are at the equator.
