A resonance tube of (closed organ pipe) air column of length 20 cm resonates with a tuning fork of frequency 250 Hz. The speed of sound in air is [in

m{s^{ - 1}}]

View answer and explanation

Correct option: B

200

Option B (200) is correct because the speed of sound can be calculated using the formula v = 4fL for a closed organ pipe at resonance.

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
