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.
