Waves unit1 flashcard review

Front

What is frequency in the context of waves?

Back

Frequency is the number of complete waves that pass a given point in one second, measured in Hertz (Hz).

Front

What happens to the crests of a wave as the wavelength decreases?

Back

The crests of the wave get closer together.

Front

What does a wave transfer from one place to another?

Back

A wave transfers energy.

Front

How does the frequency of a wave relate to its energy?

Back

A wave with a high frequency has high energy.

Front

What type of wave is characterized by particle movement parallel to the direction of wave propagation?

Back

Longitudinal wave.

Front

What is the formula to calculate the speed of a wave?

Back

Wave speed = frequency × wavelength.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive crests or troughs in a wave.

Front

What is the difference between transverse and longitudinal waves?

Back

In transverse waves, particle movement is perpendicular to wave direction; in longitudinal waves, it is parallel.

Front

What is amplitude in a wave?

Back

Amplitude is the maximum displacement of points on a wave from its rest position.

Front

What is the relationship between wavelength and frequency?

Back

As wavelength decreases, frequency increases.
