Question

a body vibrating with a time period of 1 by 256 second produce
sound by which travels in the chair with the velocity of 350 metre per second calculate the wavelength

Answer 1

As time period is nothing but the reciprocal of frequency.

f=1/1/256=256Hz

velocity = frequency x wavelength --------------> wavelength=velocity / frequency=350/256= 1.367m

Answer 2

wavelength=velocity/frequency
=350/256
=1.367m
