Two sound waves (expressed in CGS units) given by and interfere. The resultant amplitude at a place where phase difference is will be
detailed solution
Correct option is C
Resultant amplitude = a12+a22+2a1a2cosφ=0.32+0.42+2×0.3×0.4×cosπ2=0.5cmTalk 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
