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

Which of the following equations represents a wave

A pulse or a wave train travels along a stretched string and reaches the fixed end of the string. It will be reflected back with

The stationary wave y = 2a sinkx cos ωt in a closed organ pipe is the result of the superposition of y = asin( ωt-kx) and

Equation of motion in the same direction is given by y1 = Asin(wt-kx), y2 = Asin(wt-kx-Θ). The amplitude of the medium particle will be

Two waves having equations x1=asin(ωt+ϕ1),x2=asin(ωt+ϕ2) If in the resultant wave the frequency and amplitude remain equal to those of superimposing waves. Then phase difference between them is

The amplitude of a wave represented by displacement equation y = 1/√a sin ωt ± 1/√b cos ωt will be

Two identical sinusoidal waves each of amplitude 5 mm with a phase difference of π/2 are travelling in the same direction in a string. The amplitude of the resultant wave (in mm) is

A wave travels in a medium according to the equation of displacement given by y(x,t) = 0.03 sin π(2t -0.01x). Where y and x are in metres and t in seconds. The wavelength of the wave is

A plane progressive wave is represented by the equation y=0.1sin(200pit−20πx) where y is displacement in m , t in second and x is distance from a fixed origin in meter . The frequency, wavelength and speed of the wave respectively are
