Answer:

The speed of light in glass is slower

than in a vacuum due to refraction. The

speed of light in a vacuum is

approximately 299,792,458 m/s, while

in glass it is typically around

200,000,000 m/s. The exact speed

depends on the type of glass and its

refractive index, which is around 1.5 to

1.7 for glass. To calculate the speed of

light in glass, use the formula: Speed of

light in glass = Speed of light in

vacuum / Refractive index of glass. This

reduction in speed causes light to bend

or refract when passing through glass.
