Superposition of Waves

Superposition of SHM

Five sinusoidal waves have the same frequency 500 Hz but their amplitudes are in the ratio 2 : 1//2 : 1//2 :1:1 and their phase angles 0 , pi//6 , pi//3 , pi//2 and pi , respectively . The phase angle of resultant wave obtained by the superposition of these five waves is

One of the components of frequency of amplitude modulated wave (AM) formed by the superposition of message signal of frequency omega_1 on a carrier wave of frequency omega_2 is

For superposition of two waves, the following is correct

During superposition of two waves of nearly equal frequencies , beat frequency is defined as the

The ratio of maximum to minimum intensity due to superposition of two waves is 49/9 . Then, the ratio of the intensity of component waves is.
