To calculate the speed of light in a glass box, you need to know the refractive index of the glass.
The refractive index of a material is a measure of how much the speed of light changes when it passes through that material. It is denoted by the symbol "n".
The formula to calculate the speed of light in a different medium is:
Speed of light in a medium = Speed of light in a vacuum / Refractive index of the medium
Given the speed of light in air (which is approximately the same as in a vacuum) as 3.0 x 10^8 m/s, let's assume the refractive index of the glass box is 1.5.
Therefore, the speed of light in the glass box can be calculated as:
Speed of light in glass box = (3.0 x 10^8 m/s) / 1.5
Speed of light in glass box = 2.0 x 10^8 m/s
So, the speed of light in the glass box is 2.0 x 10^8 m/s.
