NEET Physics Interference MCQ Question
In Young's Double Slit Experiment, the distance between slits (d) is 0.025 mm, the distance from the slits to the screen (D) is 5 cm, and the wavelength of light (λ) is 5 × 10⁻⁵ cm. What is the distance (x) from the central bright fringe to the first-order bright fringe on the screen?
0.1 cm
0.25 cm
0.01 cm
0.5 cm
Correct Answer
Detailed Explanation
Using the formula for constructive interference x = (n * D * λ) / d with n = 1, we calculate x = (1 * 5 * 5 × 10⁻⁵) / 0.025 = 0.1 cm.
