Chapter 6.2, Problem 2CP

Interpretation Introduction

Interpretation:

The wavelength of light is to be calculated.

Concept introduction:

Light is measured by its wavelength (in nanometres) or frequency (in Hertz).

One wavelength equals the distance between two successive wave crests or troughs.

Frequency (Hertz) equals the number of waves that passes a given point per second.

The relation between the speed of light, wavelength, and frequency is as follows:

$c=v\lambda$

Here, $v$ is the frequency, $\lambda$ is the wavelength, and $c$ is the speed of light.

The frequency of electromagnetic radiation is used to determine the amount of energy carried by one of its photons.

The energy of the photon is directly proportional to frequency.

$E=hv$

Here, $v$ is the frequency, $c$ is the speed of light, $E$ is the energy, and $h$ is Plank’s constant.
