True or False , explain why
Light travels faster in vacuum than it does in a
glass.
When light enters a medium with a higher index of refraction, the ray is bent farther away from the line normal to the boundary.
The path of a ray of light between two points is the path that minimizes the travel time.
White light that is reflected from a surface will be separated into a visible spectrum.
If one stands by a swimming pool, a person standing in the pool will seem to have long legs.
