Chapter 6, Problem 119AP

Interpretation Introduction

Interpretation:

The wavelength of a proton moving at 50.0 percent the speed of light and the mass of a tennis ball moving at 63 m/s are to be determined, the results are to be explained.

Concept introduction:

The de Broglie equation is related to the particle and wave properties of the matter.

The de Broglie wavelength can be determined as follows:

$\lambda =\frac{\text{h}}{mu}$

Here, $\lambda$ is the wavelength, $\text{h}$ is Planck’s constant $\left(6.63\times {10}^{-34}\text{ J}\cdot \text{s}\right)$, $m$ is the mass of the particle in kilogram, and $u$ is the velocity of the particle.
