Two waves having equations
If in the resultant wave the frequency and amplitude remain equal to those of superimposing waves. Then phase difference between them is
detailed solution
Correct option is B
Superposition of waves does not alter the frequency of resultant wave and resultant amplitude ⇒a2=a2+a2+2a2cosφ=2a2(1+cosφ)⇒cosφ=−1/2=cos2π/3∴φ=2π/3Talk to our academic expert!

Two waves are propagating to the point P along a straight line produced by two sources A and B of simple harmonic and of equal frequency. The amplitude of every wave at P is ‘a’ and the phase of A is ahead by than that of B and the distance AP is greater than BP by 50 cm. Then the resultant amplitude at the point P will be, if the wavelength is 1 meter
