Diffraction Grating — Previous-Year Questions
4 previous-year questions on Diffraction Grating, drawn from JEE Mains, JEE Advanced, NEET UG, and CUET papers. Every question carries a worked-out explanation.
Q1. A diffraction grating has 5000 lines/cm. Find the angle of the first-order maximum for λ = 500 nm.
JEE 2021Q2. Resolving power of a grating with N = 10000 lines at first order is:
JEE 2020Q3. In a diffraction grating, the maximum order possible for λ = 600 nm and d = 1 μm is:
JEE 2018Q4. In a grating with d = 4a (slit spacing 4× slit width), the missing order is at:
JEE 2019Diffraction Grating previous-year questions from sciphylab (also known as SciPhy, SciPhy Lab, SciPhy Labs, Physics Lab). Class 12 physics practice for JEE Mains, JEE Advanced, NEET UG, AP Physics 1/2/C, SAT, and CUET-UG candidates.
