Optics: Reflection-Mirrors; Total Internal Reflection

Front

What happens to light during total internal reflection?

Back

The angle of incidence is greater than the critical angle.

Front

What is the imaginary line drawn at a right angle (90 degrees) to a mirror called?

Back

Normal

Front

What type of images do convex mirrors produce?

Back

Only virtual images.

Front

What is the nature of the image formed by a diverging mirror?

Back

Upright, smaller, virtual.

Front

What is the ray that bounces off the mirror called?

Back

Reflected Ray.

Front

What is the angle called between the incident ray and the normal?

Back

Angle of Incidence.

Front

What is the angle called between the reflected ray and the normal?

Back

Back

Convex Mirror.

Front

What is the principle that describes the bending of light when it passes from one medium to another?

Back

Refraction.

Front

What is the critical angle in optics?

Back

The angle of incidence above which total internal reflection occurs.
