Mid-Unit Review (Open Sci Ed)

Front

What happens to the frequency of a wave when its wavelength is large?

Back

The frequency is low.

Front

What is the definition of wavelength?

Back

Wavelength is a measurement of how long a wave is, typically measured from one point to the same point on the next wave.

Front

What type of sound is produced by a wave with a low frequency?

Back

Quiet, low pitch.

Front

What is frequency in terms of waves?

Back

Frequency is the number of wavelengths that pass a point each second.

Front

How does increasing the distance represented by a wave affect the sound?

Back

The sound would be louder.

Front

What is the relationship between wavelength and energy in a wave?

Back

A wave with a large wavelength has low energy.

Front

What is amplitude in the context of waves?

Back

Amplitude is the height of the wave from the rest position to the crest or trough.

Front

What is the effect of a high frequency on sound?

Back

A high frequency results in a loud, high pitch sound.

Front

What is compression in a wave?

Back

Compression is the part of a longitudinal wave where the particles are closest together.

Front

What is reflection in terms of waves?

Back

Reflection is when a wave bounces back after hitting a barrier.
