MHT CET Physics question
Two sources of sound A and B produces the wave of 350 Hz, in the same phase. The particle P is vibrating, under the influence of these two waves, if the amplitudes at the point P produces by the two waves is 0.3 mm and 0.4 mm, then the resultant amplitude of the point P will be (when AP − BP = 25 cm and the velocity of sound is )
Answer: (D)
Solution
m, so path difference m gives a phase difference and mm; 0.7
