What do you see when sunlight is refracted through water droplets?

• a wavelength

• a rainbow

• a reflection

• a light

Why do sound waves travel around corners better than light waves?

• Sound waves have longer wavelengths than light waves

• Light waves have longer wavelengths than sound waves.

• Light waves don’t bend

• Sound waves are more flexible

A wave can make a leaf bob up and down on the water, but it cannot move the leaf toward the shore. This is because waves only transfer

• matter.

• energy

• media

• crests

When two objects, such as marimba bars and columns, vibrate at the same frequency, this occurs

• refraction

• reflection

• resonance

• amplitude

Any disturbance that transmits energy is a(n)

• diffraction

• wave

• resonance

• amplitude

The maximum distance a wave vibrates from its rest position is called its

• diffraction

• wave

• resonance

• amplitude

The distance a single wave crest or trough travels in a set amount of time is a measure of the

• diffraction

• wave

• resonance

• wave speed

When two or more waves share the same space at the same time, it is called

• diffraction

• interference

• resonance

• frequency

How quickly a sound reaches your ears depends on

• how loud or soft the sound is.

• the medium through which the sound is traveling

• what causes the sound

• the properties of the sound

A measure of how high or how low a sound is perceived to be is

• its pitch

• its speed

• its frequency

• its medium
