The speed of sound in a gas of density

\rho

at a pressure

P

is proportional to

View answer and explanation

Correct option: D

\sqrt {\frac{P}{\rho }}

Option D is correct because the speed of sound in a gas is directly proportional to the square root of the pressure divided by the density, as given by the formula

v = \sqrt{{\frac{{P}}{{\rho}}}}

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
