Question

The time period of a vibrating body is 0.1 s. The waves produced by the body moves with a speed of 340 msl. Find the wavelength of the wave.​

Answer 1

Explanation:

Given,

Time period =0.01sec

We have to find the frequency.

We have the relation, Frequency=

TimePeriod

1

∴Frequency=

0.01

1

=100s

−1

Answer 2

Explanation:

T=0.1s

V=340m/s²

f=1/T

=1/0.1

=10Hz

wavelength = V/f

=340/10

=34 m
