The disc of a siren containing

60

holes rotates at a constant speed of

360

rpm. The emitted sound is in unison with a tuning fork of frequency

View answer and explanation

Correct option: B

360 Hz

Option B (360 Hz) is correct because the frequency of the emitted sound matches the tuning fork frequency when calculated from the siren's rotation speed and number of holes.

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
