Solving a problem in physics, section 41, paragraph 67

67. Two coherent sources send transverse waves in the same phase. The oscillation periods T = 0.2, the propagation velocity of waves in the medium υ = 800 m / s. Determine if a path difference in the case of superposition of waves will occur: 1) the weakening of the oscillation; 2) amplification of the oscillations.
