Q. Two waves are propagating perpendicular to each other superimpose on each other. If the initial phase difference between them is π/4, the resultant wave will be a) straight line b) parabola c) circle d) ellipse
The resultant of two waves is given byR2=A2+B2+2ABcosθ;θis the phase difference and A and B are the amplitudes of the individual waves.Ifθ=2π, thenR=A+BThe correct option is (a)
