Flashcards 4F

Front

What is a ripple tank used for?

Back

To model the behavior of waves and visualize the patterns of ripples.

Front

What is wavelength?

Back

The distance from one crest of a wave to the next.

Front

What is amplitude?

Back

The maximum distance that the surface of the water is displaced from its undisturbed level.

Front

What is frequency?

Back

The number of waves sent out each second, measured in hertz (Hz).

Front

What is the period of a wave?

Back

The time taken for one complete wave to pass a point, measured in seconds.

Front

What are transverse waves?

Back

Waves in which the particles move from side to side, at right angles to the direction of the wave.

Front

What are longitudinal waves?

Back

Waves in which the particles move back and forth along the direction of the wave.

Front

What is wave speed?

Back

The rate at which the crest of a wave travels, measured in meters per second (m/s).

Front

How is wave speed calculated?

Back

Wave speed = frequency × wavelength (v = fλ).

Front

What happens to waves when they travel from one material to another?

Back

They usually change speed, but their frequency remains unchanged.
