In a plane progressive wave given by y = 25 cos (2 πt – πx), the amplitude and frequency are respectively

Three sound waves of equal amplitudes have frequencies (v - 1), v (v + 1). They superpose to give beats. The number of beats produced per second will be

When two sound waves with a phase difference of π/2, and each having amplitude A and frequency ω, are superimposed on each other, then the maximum amplitude and frequency of resultant wave is
