If oil of density higher than water is used in place of water in a resonance tube how does the frequency change?

(A): A person hears maximum sound at displacement anti node (or) pressure node. (B) : Two organ pipes of same length open at both ends produce sound of different pitch if their radii are different. (C): If oil of density higher than water is filled in place of water in a resonance tube, its frequency remain unchanged.

If the lens is placed in water instead of air, how does its focal length change?

A solid which has density less than water is ……..

In an experiment to measure the speed of sound by a resonating air column, a tuning fork of frequency 500 Hz is used. The length of the air column is varied by changing the leavel of water in the resonance tube. Two successive resonances are heard at air columns of length 50.7 cm and 83.9 cm. Which of the following statements is (are) true?

Rate of transpiration higher than rate of water absorption shall cause

A ray of light passes from water to air, How does the speed of light change ?

A large drop of oil whose density is less than that of water, floats up through a column of water assume that the oil an the water do not mix. The coefficient of viscosity of the oil is eta_(@) and that of water is eta_(W) the velocity of the drop will depend on

The temperature of an organ pipe when it is in resonance with a tuning fork is increased. How does the resonant length change?

An open pipe of sufficient length is dipping in water with a speed v vertically. If at any instant l is lengths of tube avoce water. Then the rate at which fundamental frequency of pipe changes , is ( speed of sound = c)

Which of the following is used to separate oil from water?
