Chapter 2, Problem 2.33SP

Interpretation Introduction

Interpretation:

From the given infrared and ultraviolet lights, the light represents higher frequency, higher wavelength and greater energy has to be identified.

Concept introduction:

Frequency:

Frequency of a wave describes the number of wave peaks that pass a fixed place per unit time.

The relationship between frequency $\left(\text{ν}\right)$ and wavelength $\left(\text{λ}\right)$ is given by

$\begin{array}{l}\text{λν}\text{=}\text{c}\\ \text{Where,}\\ \text{λ}\text{-}\text{wavelength}\\ \text{ν}\text{-}\text{frequency}\text{and}\text{c}\text{-}\text{speed}\text{of}\text{light}\text{.}\end{array}$
