Waves

Refraction occurs when a wave changes its _______ as it passes through a different medium.

• color

• frequency

• intensity

• speed

Houses with carpet are much quieter than houses with tile or hardwood floors because of sound wave

• absorption

• diffraction

• reflection

• refraction

The picture shows what type of wave behavior

• absorption

• reflection

• diffraction

• refraction

An echo is an example of sound wave

• absorption

• reflection

• diffraction

• refraction

A glass prism is able to bend light because

• light is refracted as it enters a different medium

• the prism creates destructive interference

• energy is diffracted when it encounters an obstacle

• the glass and the light’s wavelength create resonance

In order for reflection to occur, the wave must an object.

• bend around

• pass through

• be absorbed by

• bounce off

The bending of light waves as they pass through one medium to another is called .

• reflection

• refraction

• diffraction

• interference
