NEET 2014 Physics Young's Double Slit Experiment MCQ Question
Type: MCQ-conceptual-Medium-Class 12
In Young’s double slit experiment, the intensity at a point on the screen where path difference λ is K. What will be the intensity at the point where path difference is λ/4?
A
K/4
B
K/2
C
K
D
Zero
Correct Answer
Option B
Detailed Explanation
The intensity in Young's double slit experiment is given by I = I₀ cos²(πΔx/λ). For Δx = λ/4, the intensity becomes I = I₀ cos²(π/4) = I₀/2, which is K/2.
