Two simple harmonic progressive waves have displacements y ₁= a ₁ ( 2 x - t ) and y ₂= a ₂ ( 2 x - t + ) What is the phase difference between two waves?

Step-by-step solution

aligned y ₁ & = a ₁ ( 2 x - t ) ...(i) y ₂ & = a ₂ ( 2 x - t + ) & = a ₂ ( 2 x - t + + 2 ) (ii) aligned From (ii) and (i) Phase difference = + 2
