An open tube is in resonance with a string. If tube is dipped in water, so that 75% of length of the tube is inside water, then ratio of frequency of tube to string is

View answer and explanation

Correct option: A

2\mathrm{ }:\mathrm{ }1

Option A (

2\mathrm{ }:\mathrm{ }1

) is correct because the frequency of an open tube is inversely proportional to its length, and the frequency of a string is independent of the tube's length.

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
