Wave Reflection, Absorption, and Transmittance

Front

What type of waves need matter to travel?

Back

Sound waves need matter to travel.

Front

What type of waves do not need matter to travel?

Back

Light waves do not need matter to travel.

Front

What is the unit of measurement for frequency?

Back

Hertz is the unit of measurement for frequency.

Front

What is a wave?

Back

A wave is a repeating pattern of motion that transfers energy from one place to another.

Front

What are the properties of waves?

Back

The properties of waves include Amplitude, Wavelength, and Frequency.

Front

What is amplitude in relation to waves?

Back

Amplitude is the height of the wave from its resting point.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive points of a wave that are in phase.

Front

What is frequency?

Back

Frequency is the number of waves that pass a point in one second.

Front

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases.

Front

What happens to sound waves when they hit a barrier?

Back

Sound waves can be reflected, absorbed, or transmitted when they hit a barrier.
