Total Internal Reflection

Measure of the bending of a ray of light when passing from one medium into another is called (a)   .

(a)   is when light reverts back to the same medium when it falls on a plane.

Reflection occurs in (a)   rather than in lenses.

When the angle of incidence exceeds the critical angle, there is no refracted light. All the incident light is reflected back into the medium from which it came. This phenomenon is called (a)   .

When the angle of incidence reaches a certain value, which is the critical angle (c), the angle of refraction is (a)   degrees..

(a)   is when light shifts direction when it enters a medium with different intensity.

The angle between the direction of motion of the wave and a line drawn perpendicular to the reflecting boundary is known as (a)   .

A (a)   is drawn perpendicular to a mirror surface at the location where a ray of light strikes the surface.

All the incident light is (a)   back into the medium from which it came, a phenomenon called total internal reflection.

When the angle of incidence reaches a certain value, called the (a)   , the angle of refraction is 90 degrees.
