MCAT RT Wave Motion and Sound 2022

If a stone is dropped in a tank of water. The waves formed on water surface is

• Longitudinal wave

• Compressional wave

• Square wave

• Transverse wave

The distance between two adjacent nodes or antinodes in a stationary wave is

• $λ$

• $λ/2$

• $λ/4$

• $2λ$

The ratio of fundamental frequency of an open-end pipe to that of a closed end pipe is

• 2 : 1

• 1 : 2

• 3:2

• 1 : 1

The fundamental frequency of a closed organ pipe is 50 Hz. The frequency of the second overtone is

• 100 Hz

• 150 Hz

• 200 Hz

• 250 Hz

A closed organ pipe and an open organ pipe have their first overtones of the same frequency. Their lengths are in the ratio:

• 1: 2

• 2 : 3

• 3 : 4

• 4 : 3

Standing waves can be produce

• On a string clamped at both the ends

• On a string clamped at one end and free at the other

• When incident waves get reflected from a wall

• All of these

“Stationary waves” are so called because in them

• The particles of the medium are not disturbed at all

• The particles of the medium do no execute SHM

• There occurs no flow of energy along the wave

• The interference effect can’t be observed

All the laws of transverse vibration of string can be verified using sonometer, which of the following law is incorrect

• $fα1/L$

• $Fα√T$

• $Fα1/√μ$

• $Fα1/T$

With the propagation of a longitudinal wave through a material medium, the quantities transferred in the direction of propagation are

• Energy, Momentum and mass

• Energy and Momentum

• Energy and Mass

• Mass

A string of length . Fixed at the two ends. Is plucked from the middle position so as to vibrate in one loop. The wave length of the wave in this mode is equal to

• $l/2$

• $l$

• $3l/2$

• $2l$
