Question
Calculate the time taken for a photon of infra-red light to travel 100 m through a vacuum
Solution
Sure, here are the steps to calculate the time taken for a photon of infra-red light to travel 100 m through a vacuum:
-
First, we need to know the speed of light in a vacuum, which is approximately 299,792 kilometers per second, or 299,792,458 meters per second.
-
Next, we need to know the distance the light is traveling, which in this case is 100 meters.
-
The time it takes for light to travel a certain distance is calculated by dividing the distance by the speed of light. In this case, time = distance / speed.
-
So, to find the time it takes for the photon to travel 100 meters, we divide 100 meters by 299,792,458 meters per second.
-
The result is approximately 0.000000334 seconds, or 334 nanoseconds.
So, a photon of infra-red light will take approximately 334 nanoseconds to travel 100 meters through a vacuum.
