Chapter 6, Problem 125AP

Interpretation Introduction

Interpretation:

The wavelength of the electrons accelerated by $5.0\times {10}^3\text{ volts}$ is to be determined.

Concept introduction:

The energy of a photon can be expressed as follows:

$\text{E}=\frac{\text{hc}}{\lambda }$

Here, E denotes the energy of a photon, $\text{h}$ denotes Planck’s constant $\left(6.63\times {10}^{-34}\text{ J}\cdot \text{s}\right)$, $\text{c}$ denotes the speed of light $\left(3.0\times {10}^8\text{ m/s}\right)$, and $\lambda$ denotes the wavelength.

Conversion of meter to picometer is as $\frac{1\text{ pm}}{1\times {10}^{-12}\text{ m}}$.
