NEET UG PHYSICS MCQ: DUAL NATURE OF RADIATION AND MATTER

1 Easy

1 of 1

Analyzing +4 | -1

Statement-1: If an electron has the same wavelength as a photon, they have the same energy.
Statement-2: By de-Broglie hypothesis,

p=h / \lambda

for both the electron and the photon.

View answer and explanation

Correct option: D

Statement-1 is false, Statement-2 is true

Option A (

{\lambda _e} < {\lambda _p}

) is not true because the de-Broglie wavelength is inversely proportional to the square root of the mass, and electrons are lighter than protons.
