Two slits 0.1 mm apart with screen 2 m away produce fringe separation with 500 nm light. The separation is :
- A 1 cm
- B 0.15 cm
- C 1.5 cm
- D 0.1 cm
Answer & Solution
Correct Answer
(A) 1 cm
Step-by-step Solution
Detailed explanation
\( \Delta y = \frac{\lambda L}{d} \) \( \Delta y = \frac{(500 \times 10^{-9} \text{ m})(2 \text{ m})}{(0.1 \times 10^{-3} \text{ m})} \) \( \Delta y = 0.01 \text{ m} = 1 \text{ cm} \)
