JEE Main 2021 — Dual Nature of Matter Question with Solution

JEE Main 2021 (27 Jul Shift 1)

Question

A particle of mass 9.1×10-31 kg travels in a medium with a speed of 106 m s-1 and a photon of radiation of linear momentum 10-27 kg m s-1 travels in a vacuum. The wavelength of the photon is ____ times the wavelength of the particle.

Correct answer
910

Step-by-step explanation

For photon λ1=hP=6.6×10-3410-27
For particle λ2=hmv=6.6×10-349.1×10-31×106
∴ λ1λ2=910
