What is the term for the number of waves that move past one spot in a second?

Back

Frequency

Front

As the wavelength in a medium increases, what happens to the speed of the wave?

Back

Speed remains the same.

Front

A wave has a frequency of 5 Hz and a speed of 25 m/s. What is the wavelength of the wave?

Back

5 m

Front

What does 'wavelength' refer to in wave physics?

Back

The distance between successive crests of a wave.

Front

What is the unit of frequency?

Back

Hertz (Hz)

Front

If the frequency of a wave doubles, what happens to the wavelength?

Back

The wavelength halves.

Front

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

Back

Wave speed (v) = frequency (f) × wavelength (λ)

Front

What happens to the speed of sound in air as temperature increases?

Back

The speed of sound increases.
