What else can I help you with?
How much time you need for 15km with the speed of light?
About 0.00005seconds in air. The spee of light in air is nearly 300000km/s. So, time required will be 15/300000 seconds which is 0.00005.
How fast can light travel in a year?
In a vacuum, light always travels at the same speed, approximately 3 x 10^8 meters/second. In a year, there are 31556736 seconds, so light travels 9.5 x 10^15 meters. That unit is called a light year. More details are available at: http://en.wikipedia.org/wiki/Light-year
Can nothingness No matter energy etc Travel faster than light If so how fast?
Think about that question. When you say nothing that means that there is nothing to measure the speed of. And nothing can move faster than light, nothing, There is a fixed amount of speed something can have. As speed increases time slows down and at light speed no time passes therefore it is impossible for anything or "nothing" in your questions case can move faster than light. Then again im only 15 so i could wrong but i am answering to the best of my knowladge.
After taking 15 index cards and piling them on top of a flashlight while in a dark room does the light stay dim after so long?
The light stay dim long as the cards is piled on top of the flash light. Human eye can adjust to see better in the dark and it might cause the thinking that after dimming by piling card over flash light for a while and it go brighter a little.
What speed does light travel at in space?
Exactly 299,792,458 meters per second. Or about 9.461 times 10 to the power 15 meters in a year.
Suppose light travels 15 times faster in a vacuum than it does in glass What is the index of refraction for glass Express your answer as a decimal?
The index of refraction for glass is 1.5. This value is calculated by dividing the speed of light in a vacuum by the speed of light in the material, which gives us 3.0 (speed in a vacuum) divided by 2.0 (speed in glass). This means light travels at 2/3 the speed in glass compared to a vacuum, resulting in an index of refraction of 1.5.
A light year is equal to?
Well depends.. If you're saying that the speed of light is 3x10^8 m/s then 1 light year is 9.46728x10^15 metres If the speed of light is exact (299,792,458m/s) then 1 light year would be 9,460,730,472,580,800 metres (9.46073x10^15) Not much difference...
How far does light travel in a femtosecond?
Femtosecond= 10^-15 secondDistance= Speed x time(10^(-15)) x the speed of light = 2.99792458 × 10-7 m / sOr about 300 nanometers.

What does high reflective index mean?
Reflective Index used to apply to CRT monitors and was a gauge of how much reflected light came off a monitor. A reflective index of < 15% was good. Today's TFT LCD monitors typically have a reflective index of less than 1%, especially those that are backlit, so the term has gone out of use now, and is no longer relevant.
How fast is mach 15?
1150.90 mph 1852.2 km/h or 0.000001716 speed of light not sure how you wanted it
Physics- What is the frequency of ultraviolet light that has a wavelength of 300 nm?
The frequency of ultraviolet light with a wavelength of 300 nm can be calculated using the equation speed of light = frequency x wavelength. The speed of light is approximately 3.00 x 10^8 m/s. By rearranging the equation, we find that the frequency is around 1.00 x 10^15 Hz.

If the price index in period 3 is 125 and the price index in period 4 is 140 the rate of inflation between period 3 and 4 is?
Final price index = 140 Initial price index = 125 Therefore, difference in price index between period 3 and 4 is : 140 - 125 = 15 Lastly, 15/125 * 100 = 12%
How long would it take to travel 15 km if you could travel at the speed of light?
Light travels 300,000 km per second.It travels 15 km in (15 / 300,000) = 5 x 10-5 = 0.00005 second(0.005 millisecond, 50 microseconds)
