NEET Physics Interference MCQ Question
In Young's Double Slit Experiment, if the slit separation d is 0.025 mm, the distance between the slits and the screen D is 5 cm, and the wavelength of light used is 5 × 10^–5 cm, what is the distance x from the central maximum to the first order bright fringe?
0.1 cm
0.5 cm
0.25 cm
0.05 cm
Correct Answer
Detailed Explanation
Using the formula x = (n * λ * D) / d for n = 1, the distance x is calculated as (1 * 5 × 10^–5 cm * 5 cm) / 0.025 mm = 0.1 cm.
