6th Grade Waves Test Review

Front

What is refraction?

Back

Refraction is the bending of a wave as it enters a new medium and changes speed.

Front

What type of wave has particles that vibrate perpendicular to the direction of the wave?

Back

A transverse wave.

Front

What causes a wave to start?

Back

A vibration.

Front

What is frequency in terms of waves?

Back

Frequency is the number of complete waves that pass a point in a certain amount of time.

Front

What is an antinode in a standing wave?

Back

The point of maximum amplitude on a standing wave.

Front

What is the difference between transverse and longitudinal waves?

Back

In transverse waves, particles move perpendicular to the wave direction; in longitudinal waves, particles move parallel to the wave direction.

Front

What is amplitude in a wave?

Back

Amplitude is the maximum distance that the particles of a medium move from their rest position.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive points that are in phase on a wave, such as crest to crest or trough to trough.

Front

What is the relationship between wave speed, frequency, and wavelength?

Back

Wave speed = frequency × wavelength.

Front

What is diffraction?

Back

Diffraction is the bending of waves around obstacles or through openings.
