An incident wave and a reflected wave are represented by xi _(1) = a "sin" (2pi)/(lambda) (vt - x) and xi _(2) = a "sin"(2pi)/(lambda) (vt + x) Derive the equation of the stationary wave and calcu-late the position of the nodes and antinodes.

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 is y = A sin 2pi (pt - x//5) . What is the ratio of particle velocity and wave velocity?

Discuss the result of superposition of two waves y_(1) = A"sin" (2pi)/(lambda_(1)) (Vt - x) and y_(2) = A "sin" (2pi)/(lambda_(2)) (Vt-x) [here lambda_(1) is slightly greater than lambda_(2) ] .

The progressive wave, is represented by the following equation — y = 20sqrt 3 sin ((2pit)/T - (2pi x)/lambda)) , find the' displacement at time t = tau//3 and x= lambda//6
