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 π/3 than that of B and the distance AP is greater than BP by 50cm. Then the resultant amplitude at the point P will be if the wavelength 1 meter

Two sources of sound A and B produce the wave of 350Hz, they vibrate in the same phase. The particle P is vibrating under the influence of these two waves. If the amplitude at the point P produced by the two waves is 0.3mm and 0.4 mm then the resultant amplitude of the point P will be: (path difference AP−BP = 25cm and the velocity of sound is 350m/sec)
