Wave Behavior

Front

What is reflection in wave behavior?

Back

Reflection is the bouncing back of a wave when it hits a surface that it cannot pass through.

Front

What happens to light when it strikes a reflective surface?

Back

Light is reflected, meaning it bounces off the surface at the same angle at which it hit.

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another, due to a change in its speed.

Front

Why does a pencil appear broken when placed in water?

Back

The pencil appears broken because light bends when it passes from air into water, causing a visual distortion.

Front

What is a convex lens?

Back

A convex lens is a lens that is thicker in the middle than at the edges and refracts light rays to converge at a focal point.

Front

What is the focal point of a lens?

Back

The focal point is the point where light rays that are initially parallel converge after passing through a lens.

Front

What is constructive interference?

Back

Constructive interference occurs when two waves meet and combine to form a wave with a larger amplitude.

Front

What is destructive interference?

Back

Destructive interference occurs when two waves meet and combine to form a wave with a smaller amplitude or cancel each other out.

Front

What is the law of reflection?

Back

The law of reflection states that the angle of incidence is equal to the angle of reflection.

Front

What is the difference between absorption and reflection?

Back

Absorption is when a wave is taken in by a material, while reflection is when a wave bounces off a surface.
