A sinusoidal progressive wave is generated in a string. It's equation is given by `y = (2mm) sin (2 pi x - 100 pi t + pi//3)` The time when particle at `x = 4 m` first passes through mean position, will be :-

A progressive wave on a string is represented by the equation y=0.2 a sin ( pi bx - 2 pi kt +(pi)/(6)) . The amplitude of the wave is

A longitudinal progressive wave is given by the equation Y=5*10^(-2)sin pi(400t+x)m .Find the wavelength in metre.

If the equation of a progressive wave is— y = 2 sin 2pi (t/4 - x/12) then what will be the displacement at x = 3m & t = 2 sec?

The equation of a progressive wave can be given by Y = 15 sin (660 pi t -0.02pi x) cm . The frequency of the wave is

A sound wave is travelling in a medium.If equation of displacement wave in the medium is given by y = 2cos ( 2 pi x - 100 pi t + pi/2 ) then equation of pressure waves will be (B rarr Bulk modulus of medium) (А) P = 4B pi sin ( 2 pi x - 100 pi t ) (В) P = 4B pi sin ( 2 pi x + 100 pi t ) (C) P = 4B pi cos ( 2 pi x - 100 pi t ) (D) P = 4B pi cos ( 2 pi x + 100 pi t )

Equation of standing waves in a string under tension T=10N is given by Y=2sin(10 pi x)sin(100 pi t) cm where x is in m and t is in second). Linear mass density of string is
