Chapter 1, Problem 1B.24E

Interpretation Introduction

Interpretation:

The average wavelength of a helium atom having average speed of $1.23\times {10}^{3}m.s^{-1}$ has to be calculated.

Concept Introduction:

de Broglie relation:

Mathematically, de Broglie relation can be represented as given below.

  $\lambda =\frac{h}{mv}$

Where, $h$ is the Planck’s constant, $\lambda$ is the wavelength of radiation, m is the mass of particle and v is the velocity of the particle.
