If the two sources of light emit waves of different amplitudes and interfere then
- A there is some intensity of light in the region of destructive interference.
- B fringe width is less.
- C brightness of fringes is less.
- D fringes disappear after short time.
Answer & Solution
Correct Answer
(A) there is some intensity of light in the region of destructive interference.
Step-by-step Solution
Detailed explanation
If \( A_1 \neq A_2 \), then for destructive interference, resultant amplitude \( A_{min} = |A_1 - A_2| \neq 0 \). Thus, there is some intensity of light in the region of destructive interference.
