Two waves having equation's x_1=asin(omegat+phi_1) , x_2=asin(omegat+phi_2) If in the resultant wave the frequency and amplitude remain equal to those of superimposing waves. Then phase difference between them is

Two waves of equal amplitude when superposed, give a resultant wave having an amplitude equal to that of either wave. The phase difference between the two waves is

Two waves, travelling in the same direction through the same region, have equal frequencies, wavelengths and amplitudes. If the amplitude of each wave is 4 mm and the phase difference between the waves is 90^@ , what is the resultant amplitude ?

If x=a sin(omegat+(pi)/6) and x= a cos omegat , then what is the phase difference between the two waves?

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