The path difference between two waves y₁=a₁ ( t- 2 x ) and y₂=a₂ ( t- 2 x + ) is

Step-by-step solution

Given, y₁=a₁ ( t- 2 x ) and y₂=a₂ ( t- 2 x + )=a₂ ( 2 + t- 2 x + ) Phase of first wave, ₁= ( t- 2 x ) and phase of second wave, ₂= 2 + t- 2 x + Phase difference, = ₂- ₁= 2 + aligned Path difference & = 2 phase difference & = 2 ( 2 + ) aligned
