Two sound waves each of wavelength ' ' and having the same amplitude ' A ' from two source ' S ₁ ' and ' S ₂ ' interfere at a point P . If the path difference, S ₂ P - S ₁ P = / 3 then the amplitude of resultant wave at point ' P ' will be [ (120^ )=-0.5 ]
Options
- AA
- B2 ~A
- CA 2
- D3 ~A 2
Correct answer
A. A
Step-by-step solution
array ll & Path difference = 3 & Phase difference = 2 3 = 2 3 =120^ & Resultant amplitude & R = A ₁^2+ A ₂^2+2 ~A ₁ ~A ₂ & Since, A ₁= A ₂ & R = A ^2+ A ^2+2 ~A ^2 120^ & R = A ^2+ A ^2+2 ~A ^2 (- 1 2 ) & R = A array
