Over time, the heat produced causes the filament to grow thinner. This causes the light bulb to grow dim.

∙ 11y agoWhen bulbs are connected in series, the voltage across each bulbs also gets divided and hence the light goes dim.

What is a stimuli for light?
i think it's plants. plants are stimulus to light ans as a result always grow in the dierction of light...
How does different light affects things?
Visible light consists of a number of wavelengths. Blue light is the most energetic, red light the least energetic. Green plants grow best in red or blue light (sunlight is a mixture of wavelengths) and do not grow in green or yellow light. Light intensity will affect the growth of plants. Laser light (high intensity with very narrow wavelength) can be used to cut and obviously hurt if used incorrectly. Some people are photo sensitive and light can cause them pain. Green plants are photo sensitive and will grow towards the light.
If a plant was growing bent over towards the light how could you make it grow straight again?
put more light
How do you make a homemade rheostat?
use a small battery, nine volt or six...make sure you have the proper bulb for the max. voltage. Split a common pencil to expose the grafite core. One wire taped to the exposed end of the pencil and to the battery. To the other post of the battery connect a second lead. By sliding the second lead back and forth on the surface of the pencil the bulb will grow brighter and dimmer based on proximity to the other lead (taped to the end of the pencil)...or replace the pencil with an old door spring. It will work in a similar fashion. Low voltage, no danger, good presentation of electrical resistance. Appropriate for middle school students to do.
Can some minerals glow under ultraviolet light?
Yes. Only certain minerals will glow under ultraviolet light. First you have to have the uv light shining on it, then you have to turn the lights off and they will grow
Does the light of a light bulb make the grass grow faster?
a regular light bulb-no.
What light is better a fluorescent light or incandescent light to grow a plant?
Definitely fluorescent. Incandescent lights are extremely inefficient and spend most of their energy producing heat rather than light. This is why an incandescent lightbulb gets so much hotter than a fluorescent one.
Will a condensed fluorescent bulb work as a grow light for garden?
Only if you buy a "full spectrum" of "grow light" type of compact bulb.
Will a regular led light bulb work as a grow light?
Yes you can use it.
How many lumens are in a 60 watt incandescent grow light?
It's about 600 lumens. The same brightness comes from a 12 Watt compact fluorescent light (CFL).
Does a plant grow better in sunlight or light bulb light?
Depends on the plant some grow better in darker places but if it needs light go with the sun it's free
What are the advantages and disadvantages of using compact fluorescent light bulbs?
One nice thing about light bulbs is that they provide light indoors and when it is dark outside, without having to light a candle or an oil lamp. They are also relatively safe, clean and easy to operate. Disadvantages include the fact that you will need electricity and wires that are properly installed and cannot be easily moved about. It is also difficult to repair a broken light bulb or one that has burned out, and they must be disposed of and replaced.
Does a light bulb have an affect on plant growth?
sure, it emits light as well as heat. the light from a regular light bulb is not sufficient for photosynthesis but may have an effect on photoperiod which can be a good or a bad things, depends on what you want to grow
Can you see a video of a regular light bulb weed grow?
I'm sure you can on the internet :)
Can plants grow under regular light-bulbs?
Explain why light is essential for a plant to grow
Do plants underneath Natural sunlight or underneath a light bulb grow best?
By studies, plants grow underneath natural sunlight better.
Why does light from the sun help plants grow but light from lamps does not?
Actually, light from certain lamps does help plants grow. In almost any garden shop, you can find germination kits that include little containers for the seedlings and a special bulb that helps grow the seedlings. In extreme cases, seen often on the news, marijuana growers actually grow entire "fields" of plants indoors using Grow Lights. Right now, in many of the catalogs you see like Brookstone etc., there's a new product that's designed to grow herbs for the kitchen?and it also uses a special Grow Bulb (and hydroponics) to achieve this. The trick is to have a bulb that covers the correct spectrum of light!
