Question:medium
A light ray incident on a slab of refractive index \( \frac{3}{2} \). If the wavelength of the refracted ray is 520 nm, find the wavelength of the incident ray.
A light ray incident on a slab of refractive index \( \frac{3}{2} \). If the wavelength of the refracted ray is 520 nm, find the wavelength of the incident ray.
Show Hint
The wavelength of light decreases in a medium with a refractive index greater than 1. Use the refractive index to find the incident wavelength.

- A monochromatic light is incident on a metallic plate having work function \( \phi \). An electron, emitted normally to the plate from a point A with maximum kinetic energy, enters a constant magnetic field, perpendicular to the initial velocity of the electron. The electron passes through a curve and hits back the plate at a point B. The distance between A and B is:

Uniform magnetic fields of different strengths $ B_1 $ and $ B_2 $, both normal to the plane of the paper, exist as shown in the figure. A charged particle of mass $ m $ and charge $ q $, at the interface at an instant, moves into region 2 with velocity $ v $ and returns to the interface. It continues to move into region 1 and finally reaches the interface. What is the displacement of the particle during this movement along the interface?
Consider the velocity of the particle to be normal to the magnetic field and $ B_2 > B_1 $.- JEE Main - 2025
