Refraction - III

Refraction III

When light passes from one material into another at an angle, it bends. This is called refraction. To understand it better, you can label the parts of the light's path. The light that first hits the boundary is called the incident ray. The line drawn at a right angle to the surfac...

Imagine a laser beam hitting a flat glass slab. Some light reflects off the surface, while the rest enters the glass and bends. This phenomenon is called refraction.

The light that strikes the boundary between air and glass is called the incident ray. At this point of contact, an imaginary perpendicular line is drawn—this is called the nor...
