Wave Speed

Front

What is a medium?

Back

The substance through which a wave can travel.

Front

What is the formula to calculate wave speed?

Back

Wave Speed = Frequency × Wavelength.

Front

What is frequency?

Back

The number of waves that pass a point in one second, measured in Hertz (Hz).

Front

What is wavelength?

Back

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

Front

How do you calculate the frequency of a wave if you know the period?

Back

Frequency = 1 / Period.

Front

If a wave has a frequency of 3 Hz and a wavelength of 2 m, what is its speed?

Back

Speed = 3 Hz × 2 m = 6 m/s.

Front

What is the relationship between frequency and wavelength?

Back

As frequency increases, wavelength decreases, and vice versa, for a constant wave speed.

Front

What is the unit of wave speed?

Back

Meters per second (m/s).

Front

If a wave travels at a speed of 150 m/s and has a frequency of 50 Hz, what is its wavelength?

Back

Wavelength = Speed / Frequency = 150 m/s / 50 Hz = 3 m.

Front

What is the significance of a wave's amplitude?

Back

Amplitude is the maximum displacement of points on a wave from its rest position, related to the energy of the wave.
