.
An object is vibrating 6600 vibrations per
minute. If the velocity of sound in air is 330 m/s
then find:
(i) Time period (ii) Frequency $
(iii) Wave length
The time period of a body is







0.004 s. Find its
2.​

Answer 1

Answer:

i) time period = no of vibrations in one second

so, 6600/60s=110 vibrations/s

ii) frequency =no of vibrations\ total time

so, 6600/60s=110 vibrations/s

iii) wave length=speed\frequency

330/110=3m
