Waves Test - 87...

Apparatus used to find out the velocity of sound in gas is

Standing stationary waves can be obtained in an air column even if the interfering waves are

The stationary wave y = 2a sin kx cos wt in a closed organ pipe is the result of the superposition of y y = a sin (ω t – kx) and

Stationary waves are set up in air column. Velocity of sound in air is 330 m/s and frequency is 165 Hz. Then distance between the nodes is

An open pipe of length 1 vibrates in fundamental mode. The pressure variation is maximum at

Fundamental frequency of pipe is 100 Hz and other two frequencies are 300 Hz and 500 Hz then

On producing the waves of frequency 1000 Hz in a Kundt\'s tube, the total distance between 6 successive nodes is 85 cm. Speed of sound in the gas filled in the tube is

What is the base frequency if a pipe gives notes of frequencies 425, 255 and 595 and decide whether it is closed at one end or open at both ends?

A student determines the velocity of sound with the help of a closed organ pipe. If the observed length for fundamental frequency is 24.7 m, the length for third harmonic will be

An open pipe of length 33 cm resonates with frequency of 100 Hz. If the speed of sound is 330 m/s, then this frequency is
