Do you observe any relation between the frequency of generated sound and the height of the air column in the glass cup?

A long capillary tube of radius 0.2 mm is placed vertically inside a beaker of water. If the surface tension of water is 7.2xx10^(-2)N//m the angle of contact between glass and water is zero, then determine the height of the water column in the tube.

Answer the following What is the relation between frequency and time period of a sound wave?

Derive the relation between velocity, frequency and wavelength of a wave. A certain sound waves in air has a speed 340 m//s and wavelength 1.7m. For this wave calculate the frequency and time period.

A siren emitting a sound of frequency 800 Hz moves away from an observer towards a cliff at a speed of 15 ms^(-1) . Then, the frequency of sound that the observer hears in the echo reflected from the cliff is (Take velocity of sound in air = 330 ms^(-1) )

The difference between the frequencies of the first and second overtones of an air column closed at one end is 280 Hz. Find the frequency of its third overtone.

An air column is of length Activity 17 cm long. Calculate the frequency of 5th overtone if the air column is open at both ends. (Velocity of sound in air = 340 ms^-1 ).

An air column is of length Activity 17 cm long. Calculate the frequency of 5th overtone if the air column is closed at one end (Velocity of sound in air = 340 ms^-1 ).

The difference between the apparent frequency 71. of a source of sound as perceived by the observer during its approach and recession is 2% of the frequency of the source. If the speed of sound in air is 300 ms^(-1) , then the velocity of the source is

The velocity of sound in air at room temperature is 350 m/s .Find the frequency of second overtone of air column of length 70 cm when it is closed at one end.
