Wavelength, Frequency, and Wave Speed

Front

What is frequency?

Back

The number of waves that pass a fixed point in a certain amount of time, measured in Hertz (Hz).

Front

What is the formula to calculate wave speed?

Back

Wave speed = Wavelength x Frequency.

Front

What is wavelength?

Back

The distance between successive crests (or troughs) of a wave, usually measured in meters.

Front

How do you calculate the speed of a wave if you know its frequency and wavelength?

Back

Multiply the frequency (in Hz) by the wavelength (in meters).

Front

If a wave has a frequency of 10 Hz and a wavelength of 2 m, what is its speed?

Back

20 m/s.

Front

What is the unit of measurement for frequency?

Back

Hertz (Hz), which is equivalent to cycles per second.

Front

If a wave travels at a speed of 30 m/s and has a frequency of 6 Hz, what is its wavelength?

Back

5 m.

Front

What happens to the wavelength if the frequency of a wave increases while the speed remains constant?

Back

The wavelength decreases.

Front

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

Back

They are inversely related; as frequency increases, wavelength decreases if speed is constant.

Front

What is wave speed in the context of sound waves?

Back

The speed at which sound waves travel through a medium, which can vary based on the medium.
