NEET 2015 Physics Young's Double Slit Experiment MCQ Question
Type: MCQ-conceptual-Medium-Class 12
In a double slit experiment, the two slits are 1 mm apart and the screen is placed 1 m away. A monochromatic light of wavelength 500 nₘ is used. What will be the width of each slit for obtaining ten maxima of double slit within the central maxima of single slit pattern?
A
0.2 mm
B
0.1 mm
C
0.5 mm
D
0.02 mm
Correct Answer
Option D
Detailed Explanation
The width of each slit can be calculated using the formula for the width of the central maximum in a single slit diffraction pattern, which is given by W = λL/a, where λ is the wavelength, L is the distance to the screen, and a is the slit separation. Solving gives 0.1 mm.
