Question

Six waves occupied a distance of 60 cm. If the period of each wave is 0.50 s, what is the wavelength?

Answer 1

10 cm

Explanation:

If six complete wavelengths occupy 60 cm, then one wavelength is `= (60" cm")/6 = 10" cm"`

The period is not relevant for the wavelength, although it does tell us that the frequency of the wave is 2 Hz, and thus its speed is 20 cm/s.
