What is a Longitudinal Wave?

• A wave that vibrates the medium in the same direction in which the wave travels

• A wave that vibrates the medium at right angles, or perpendicular to the direction that the wave travels.

What is the relationship between a wave’s frequency and a wave’s wavelength?

• The higher the frequency of a wave, the shorter its wavelength.

• The shorter the frequency of a wave, the shorter the wavelength.

• The longer the frequency of a wave, the longer its wavelength.

• The higher the frequency of a wave, the higher its wavelength.

What causes refraction?

• When light travels from air to water, it slows down, causing it to slightly change direction. The speed changes.

• When light travels from air to water the light changes causing it to look different.

• When a light wave breaks or has a glitch it causes a refraction.

• When the color waves change as they go to the water it makes it appear different.
