Textbook Problem

An electron moves with a velocity of 2.5 X 108 cm/s. What is its wavelength?

Interpretation Introduction

Interpretation: The wavelength associated with an electron has to be calculated.

Concept introduction:

The de Broglie’s equation is used to relate the wavelength to mass of a particle and the velocity at which it moves.

  λ=hmvwhere, h=Planck'sconstantλ=wavelengthm=massoftheparticlev=velocityatwhichtheparticlemoves

Explanation

The wavelength associated with an electron is calculated below.

Given,

  Massoftheelectron=9.11×1031kgPlanck'sconstant,h=6.626×1034J.sVelocityoftheelectron, v=2.5×108cm/s=2.5×106m/s

According to de Broglie’s equation, wavelength associated with an electron is,

  λ=hmv=6.626×1034J.s9.11×1031kg×2.5×106m/s=2
