If the light is in a vacuum then it would take around 0.00000033 seconds.
Frequency = (speed)/(wavelength) = 299,792,458/100 = 2,997,924.58 Hz.
BTW . . . Photons always move at the speed of light.
Simply divide the 100 meters by the speed of light, which is approximately 300,000,000 meters/second. The answer will be in seconds.
3 or 2 minute take to this distance.
At 25 meters per second a car will travel 100 meters in 4 seconds and 1000 meters in 40 seconds.
I make the distance from Perth to Brisbane to be about 3,613.9 kilometers (2,246 miles).The speed of light is 299,792,458 meters per second.At that speed, the trip takes (3,613,900 / 299,792,458) = 0.012 second(12,054,672 nanoseconds . . . 12,054 microseconds)
How much time would it take for the sound of thunder to travel 2000 meters if sound travels a speed of 330 meters per sec.
(455) / (3 x 108) = 1.52 microseconds (rounded)
It will take 3.3 seconds to travel 44 meters at 48kph.

First of all, the speed of light is 3 x 108 meters per second, not 3 x 105.It will take 10 milliseconds for a ray of light to travel 3 x 106 meters at a speed of 3 x 108 meters per second.If the number in the question were correct, which they are not, the answer would be ten seconds.
1000.3848995m/s
3 or 2 minute take to this distance.
It will take 1 year, as soon as you and Albert work out how to travel at the speed of light. ;)
Take 200 divide by 20!
You're asking how long it takes light and heat to travel from the sun to the earth, but mixing your units.The "299 ... ...' is the speed of light in meters per second, and the "93 ... ..." is the distance in miles.The answer is still 8-1/3 minutes.
A lightyear is the distance that light can travel in one year.
it would take 75 seconds
8.52 seconds
It takes light exactly one hour to travel in 1 hour.
