Light Review

Front

What is a convex mirror?

Back

A convex mirror is a curved mirror that bulges outward. It reflects light outward and is used to provide a wider field of view, such as in car side mirrors.

What are the three types of objects based on their interaction with light?

Back

Objects can be classified as transparent (allowing light to pass through), translucent (allowing some light to pass through), or opaque (not allowing light to pass through).

Front

What happens to light when it strikes a plane mirror at a 45° angle?

Back

The light will reflect off the mirror at the same angle of 45°, following the law of reflection which states that the angle of incidence equals the angle of reflection.

Front

What is a plane mirror?

Back

A plane mirror is a flat mirror that reflects light to form a virtual image that appears the same size as the object.

Front

What is a convex lens?

Back

A convex lens is a lens that is thicker in the middle than at the edges. It converges light rays that are coming in parallel to the lens.

Front

What is the law of reflection?

Back

The law of reflection states that when light hits a reflective surface, the angle of incidence is equal to the angle of reflection.

Front

What is the difference between transparent and opaque objects?

Back

Transparent objects allow light to pass through them completely, while opaque objects do not allow any light to pass through.

Front

What is an example of a translucent object?

Back

Frosted glass is an example of a translucent object; it allows some light to pass through but scatters it, making objects on the other side appear blurry.

Front

How does a concave mirror differ from a convex mirror?

Back

A concave mirror curves inward and can focus light to a point, while a convex mirror curves outward and spreads light rays apart.

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another, such as from air to water.
