MHT CET Physics question
Two waves are propagating to the point P by two sources A and B 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. If the wavelength is 1 m, then the resultant amplitude at the point P will be
Answer: (D)
Solution
The extra path m introduces a phase lag of for A, which together with its lead of gives a net phase
