Front

The number of waves that pass a fixed point in 1 second is called __________.

Back

Frequency

Front

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

Back

c = λf (where c is the speed, λ is the wavelength, and f is the frequency)

Front

What is the relationship between frequency and wavelength?

Back

As frequency increases, wavelength decreases.
