Physics: Sound Wave MCQs

A wave is represented by the equation

y= 7 sin(7πt-0.04x+π/3), where x is in meters and t is in seconds.The speed of the wave is,

Two waves having intensities in the ratio of 9:1 produce interference. The ratio of maximum to minimum intensity is equal to

Two tuning forks of frequencies 256 and 258 vibrations/second are sounded together. Then the time interval between two consecutive maxima heard by an observer is

Two waves are y₁ = 0.25 sin 316t,

y₂ = 0.25 sin 30t are travelling in the same direction. The number of beats produced per second will be

What is the phase difference between two successive troughs in the transverse wave?
