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

Each of the two strings of length 51.6 cm and 49.1 cm are tensioned separately by 20 N force. Mass per unit length of both the strings is same adn equal to 1 gm^-1. When both the strings vibrate simultaneously the number of beats will be:

The velocity of sound in any gas depends upon:

Two periodic waves of intensities I₁ and I₂ pass through a region at the same time in the same direction. The sum of the maximum and minimum intensities will be:

Two vibrating tuning forks produce progressive waves given by y₁ = 4 sin 500 πt and y₂ = 2 sin 506 πt. Number of beats produced per minute is:

For production of beats the two sources must have:

A wave enters to water from air. In air frequency, wavelength, intensity and velocity are n₁, λ₁, l₁ and v₁ respectively. In water the corresponding quantities are n₂, λ₂, l₁and v₂ respectively, then:

The wave described by

        y = 0.25 sin (10πx - 2πt),

where x and y are in metre and t in second, is a wave travelling with :

Equation of progressive wave is given by

Then which of the following is correct?

A stretched string resonates with tuning fork frequency 512 Hz when length of the string is 0.5 m. The length of the string required to vibrate resonantly with a tuning fork of frequency 256 Hz would be:
