Two progressive waves y_(1) = 4 sin 400 pi t and y_(2) = 3 Sin 404 pi t moving in the same direction superpose on each other producing beats. Then the number of beats per second and the ratio of maximum to minimum intensity of the resultant waves are respectively

Two progressive transverse waves given by y_(1) =0.007 sinpi ( 12x- 500 t ) and y _(2) = 0.07 sin pi ( 12x+500t) travelling along a stretched string from nodes and antinodes . What is the displacement at the (a) nodes (b) antinodes ? What is the wavelength of the standing wave ?
