Question

A sound has a frequency of 50 Hz and a wavelength of 10 m. What is

the speed of the sound?​

Answer 1

Answer:

the wavelength of a sound wave is 6.84 meters.

Answer 2

So, the wavelength of a sound wave is 0.02s meters

Explanation:

The period is the duration of time of one cycle in a repeating event, so the period is the reciprocal of the frequency.

Here, a sound wave is vibrating at frequency 50 Hz. Hence, the time period T = 1/f = 1/50 = 0.02 s.

Hence, the sound wave vibrating at frequency 50 Hz has a time period of 0.02 s.
