STANDARD Physics Interference MCQ Question
In Young's double slit experiment two disturbances arriving at a point P have phase difference of π/3. The intensity of this point expressed as a fraction of maximum intensity I₀ is
3/2 I₀
1/2 I₀
4/3 I₀
3/4 I₀
Correct Answer
Detailed Explanation
The resultant intensity I = I₀ cos²(φ/2). With φ = π/3, I = I₀ cos²(π/6) = I₀ (3/4).
