10 beats/ are produced by the superposition of two sound waves. If the equation of the first wave is y_(1) = 5 sin 20 pi (30t) , then the equation of second wave is

The equation of a sound wave is y = 0.0015 sin (62.4x + 316 t) The wavelength of this wave is

The equation of a progressive wave is given by, y = 5 sin pi ((t)/(0.02) - (x)/(20)) m, then the frequency of the wave is

On the superposition of two waves [y_1 = 3 sin (50 pi t - 20x)] and [y_2 = 3sin (50pi t -20 x +(pi/3)] the equation resultant wave will be

On the superposition of two waves [y_1 = 3 sin (50 pi t - 20x)] and [y_2 = 3sin (50pi t -20 x +(pi/3)] the equation resultant wave will be

The equation of wave is y=1.0 cos 2pi(t/0.02-x/10) where t is in second. The frequency of the wave is

From a wave equation y= 0.5 sin ((2pi)/3.2)(64t-x). the frequency of the wave is
