The wavelength of two notes in air are

\frac{{36}}{{195}}m

and

\frac{{36}}{{193}}m

each note produces

10

beats per second separately with a third note of fixed frequency. The velocity of sound in air in

m/s

View answer and explanation

Correct option: D

360

Option D (

360

) is correct because it is calculated by finding the frequencies from the wavelengths and then using the beat frequency to determine the velocity of sound.

sound wave in air strikes the surface of a lake and penetrates into water. If speed of sound in water is

1500\,\,\mathrm{m}{\mathrm{s}^{ - 1}}

, the frequency and wavelength of waves in water are The equation for spherical progressive wave is (where

r

is the distance from the source) One metre long tube, closed at both ends, is lying horizontally. A mercury column of length 0.1m is filled in its middle and in rest two parts air is filled at atmospheric pressure. When tube is turned to vertical position, then displacement of mercury will be (standard pressure = 0.76 m of Hg) A tuning fork produces waves in a medium. If the temperature of the medium changes, then which of the following will change In a stationary wave all the particles A SONAR system fixed in a submarine operates at a frequency
