Two sound waves (expressed in CGS units) given by ` y_(1)=0.3 sin (2 pi)/(lambda)(vt-x) and y_(2)=0.4 sin (2 pi)/(lambda)(vt-x+ theta)` interfere. The resultant amplitude at a place where phase difference is ` pi //2 ` will be

Two coherent waves represented by y_(1) = A sin ((2 pi)/(lambda) x_(1) - omega t + (pi)/(4)) and y_(2) = A sin (( 2pi)/(lambda) x_(2) - omega t + (pi)/(6)) are superposed. The two waves will produce

Two waves are passing through a region in the same direction at the same time . If the equation of these waves are y_(1) = a sin ( 2pi)/(lambda)( v t - x) and y_(2) = b sin ( 2pi)/( lambda) [( vt - x) + x_(0) ] then the amplitude of the resulting wave for x_(0) = (lambda//2) is

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.
