NEET Physics Interference MCQ Question
In Young's double-slit experiment, if the distance between the slits (d) is 0.025 mm, the wavelength of light (λ) is 5 × 10^-5 cm, and the distance to the screen (D) is 5 cm, what is the distance (x) between the central bright fringe and the first-order bright fringe?
1 mm
0.5 mm
2 mm
0.25 mm
Correct Answer
Detailed Explanation
Using the formula x = nDλ/d for the first-order bright fringe (n=1), x = (1)(5 cm)(5 × 10^-5 cm) / 0.025 mm = 1 mm.
