Waves Test Review

What is the definition of frequency?

• The number of vibrations or cycles per unit time.

• The total amount of energy in a system.

• The speed of sound in a medium.

• The distance traveled by a wave in one cycle.

What determines the energy a wave carries?

• The frequency.

• The wavelength.

• The amplitude.

• The speed.

What is refraction?

• The bending of a wave as it passes from one medium to another.

• The reflection of light off a surface.

• The absorption of light by a material.

• The scattering of light in different directions.

What is a wave?

• A disturbance that transfers energy from one place to another.

• A type of particle that moves through a medium.

• A static force that does not change over time.

• A phenomenon that only occurs in liquids.

What is the relationship between amplitude and energy?

• Higher amplitude means more energy.

• Higher amplitude means less energy.

• Amplitude has no effect on energy.

• Amplitude and energy are unrelated.

What are the two main types of waves?

• Transverse waves and longitudinal waves.

• Sound waves and light waves.

• Radio waves and microwaves.

• Surface waves and bulk waves.

What is a longitudinal wave?

• A wave where the particles of the medium move perpendicular to the direction of the wave.

• A wave where the particles of the medium move parallel to the direction of the wave.

• A wave that travels through a vacuum without a medium.

• A wave that oscillates in two dimensions.

What does a prism allow you to do?

• Separate white light into different colors.

• Reflect light without changing its color.

• Increase the brightness of light.

• Focus light into a single beam.

What is the correct formula for amplitude?

• The maximum displacement of a wave.

• The frequency of the wave.

• The speed of the wave.

• The wavelength of the wave.

How do transverse waves move?

• In a circular pattern.

• In a straight line.

• In an up and down pattern.

• In a side to side motion.
