Question

A vibrator of frequency 20Hz produces waves of velocity 2m/s. Find the period of the waves

Answer 1

Answer:

If we use 20 Hz. as our frequency, we take the speed of sound 1130 ft./sec. and divide it by 20. Our answer is 56.5 ft.

Answer 2

Answer:

0.1meters

Explanation:

v=lamda×mue

velocity=wavelength×frequency

2=wavelength×20

wavelength=2/20=1/10=0.1
