The resultant amplitude, when two waves of two waves of same frequency but with amplitudes `a_(1)` and `a_(2)` superimpose at phase difference of `pi//2` will be :-

If two waves of same frequency and same amplitude superimpose and produce third wave of same amplitude, then waves differ in phase by –

Two waves of the same frequency have amplitudes 2 and 4. They interfare at a point where their phase difference is 60^(@) . Find their resultant amplitude.

When two waves of the same frequency and same amplitude ‘a’ are superposed in phase, the resulting intensity at the point of superposition is proportional to

Three waves producing displacement in the same direction of same frequency and of amplitudes 10etam, 4etam" and "7eta m arrive at a point with successive phase difference of pi//2 . The amplitude of the resultant wave is :--

Two waves of same frequency but of amplitude a and 2a respectively superimpose over each other. The intensity at a point where the phase difference is (3pi)/(2) , will be proportional to :

The amplitude factor of resulting wave, formed by superposition of two sinusoidal waves of equal amplitude a and constant phase difference is given by

Represent graphically by two separate diagrams in each case : (i) Two sound waves having the same amplitude but different frequencies. (ii) Two sound waves having the same frequency but different amplitudes. (iii) Two wound waves having different amplitudes and also different wavelengths.
