Two points lie on a ray are emerging from a source of simple harmonic wave having period 0.040. The wave speed is 300 m/s and points are at 10 m and 16 m from the source. They differ in phase by:

Sound wave from a point source are propagating in all directions. What will be ratio of amplitudes at distances of 9 m and 25 m from the source?

Two sound sources oscillate in phase with a frequency of 100 Hz. At a point 1.74 m from one source and 1.16 m from the other, the amplitudes of sound from the two sources are A and 2 A respectively. Calculate the amplitude of the resultant disturbance at the point. [Speed of sound in air is v = 348 ms^( –1) ]
