A standing wave is formed by the superposition of two waves travelling in
opposite directions. The transverse displacement is given by

y(x, t) = 0.5 sin $$\left( {{{5\pi } \over 4}x} \right)\,$$ cos(200 $$\pi $$t).

What is the speed of the travelling wave moving in the positive x direction ?

(x and t are in meter and second, respectively.)

Two wires W

_{1}and W_{2}have the same radius r and respective densities $$\rho $$_{1}and $$\rho $$_{2}such that ρ_{2}= 4$$\rho $$_{1}. They are joined together at the point O, as shown in the figure. The combination is used as a sonometer wire and kept under tension T. The point O is midway between the two bridges. When a stationary wave is set up in the composite wire, the joint is found to be a node. The ratio of the number of antinodes formed in W_{1}to W_{2}is :Questions Asked from Waves (MCQ (Single Correct Answer))
