If two waves having amplitudes 2 A and A and same frequency and velocity, propagate in the same direction in the same phase, the resulting amplitude will be

If two waves having amplitudes 2A and A and same frequency and velocity, propagate in the same direction in the same phase, the resulting amplitude will be

Two waves of equal amplitude A, and equal frequency travel in the same direction in a medium. The amplitude of the resultant wave is

Two waves of equal amplitude A, and equal frequency travel in the same direction in a medium. The amplitude of the resultant wave is

Two waves of equal amplitude A, and equal frequency travel in the same direction in a medium. The amplitude of the resultant wave is

Two sinusoidal wave having the same frequency and travelling in the same direction are combined. What is the amplitude of the resultant motion if their amplitudes are 3cm and 4cm and they differ in phase by pi//2 radian?

Two waves are propagating with same amplitude and nearly same frequency in opposite direction, they result in

Two waves of equal frequency f and velocity v travel in opposite directions along the same path. The waves have amplitudes A and 3 A . Then:

Can two waves of the same frequency and amplitude travelling in the same direction give rise to a stationary wave after superposition ?
