Two identical light waves having phase difference propagate in same direction. When they superpose, the intensity of resultant wave is proportional to
Options
- A^2 ( 4 )
- B^2 ( 3 )
- C^2 ( 2 )
- D^2 .
Correct answer
C. ^2 ( 2 )
Step-by-step solution
A^2=a₁^2+a_i^2+2 a₁ a₂ , where A is amplitude of resultant wave and given that, a₁=a₂=a , where, a is amplitude of individual wave. array ll & A^2=2 a^2(1+ )=2 a^2 (1+2 ^2 2 -1 ) & A^2 ^2 2 array Now, I ~A ^2 I A^2 ^2 2 I ^2 2
