Question

Assume that light travels faster through air than it does through glass, make a generalized statement about what happens to a light ray with respect to the normal as it moves from a faster speed in one material to a slower speed in another.

Answer 1

When a light ray moves from a faster speed in one material to a slower speed in another, it bends towards the normal. This phenomenon is known as refraction.

Step-by-step explanation:

When a light ray moves from a faster speed in one material to a slower speed in another, it bends towards the normal. The normal is an imaginary line perpendicular to the boundary between the two materials. This phenomenon is known as refraction.

For example, when light goes from air to glass, it slows down because the speed of light is slower in glass than in air. As a result, the light ray bends towards the normal at the boundary between air and glass.

Refraction plays a crucial role in various applications, such as lenses, prisms, and fiber optics.
