What is the period of a wave with a wavelength of 8 cm and a frequency of 0.5 Hz

The formula to calculate the period (T) of a wave is:

T = 1/f

where T is the period and f is the frequency.

Given the wavelength (λ) of the wave is 8 cm and the frequency (f) is 0.5 Hz:

T = 1/f
T = 1/0.5
T = 2 seconds

Therefore, the period of the wave is 2 seconds.
