Light and Sound Test

Front

What happens to colors when light strikes a black surface?

Back

All colors are absorbed, causing the surface to heat up.

Front

What type of lens is used to converge light rays?

Back

Convex lens.

Front

What type of lens is used to diverge light rays?

Back

Concave lens.

Front

What type of mirror produces a regular image with no change?

Back

Plane mirror.

Front

What type of image does a concave mirror produce when the object is close?

Back

Bigger and upright.

Front

What is the angle of reflection in relation to the angle of incidence?

Back

The angle of reflection is equal to the angle of incidence.

Front

What type of image does a convex mirror produce?

Back

Smaller and upright image.

Front

What is the normal line in optics?

Back

An imaginary line perpendicular to the surface at the point of incidence.

Front

What is the law of reflection?

Back

The angle of incidence equals the angle of reflection.

Front

What is a plane mirror?

Back

A flat mirror that reflects light to form a regular image.
