Question

a body vibrating with the time period of 5 into 10 raise to power minus 3 second produces a wave travelling in a medium with the velocity is equals to 1450 metre per second calculate its wavelength and frequency​

Answer 1

Answer:Frequency = 200 Hz and Wavelength = 7.25Hz

Explanation:

Given- time period T= 5x$10^{-3}$

and Frequency= 1/T

So, the frequency F= 0.2 x $10^{3}$ Hz = 200 Hz

Also,

Velocity V=υ x λ

Where υ is the frequency and λis your wavelength.

So, 1450m/s= 0.2 x 1000 x λ

λ= 7.25 m
