Question

A closed organ pipe of length 20cm is sounded with turning fork in resonance. What is the frequency of turning fork? (guven=332ms

Answer 1

Given :

speed of sound (v)= 332m/s

wavelength(w) = 20cm= 0.2m

using the formula V= f×w;

frequency = v/w

= 332/0.2

= 1660 Hz

HOPE THIS HELPED YOU!!!
