# 5.1: The Nature of Light

Difficulty Level: At Grade Created by: CK-12

## Student Behavioral Objectives

The student will:

• perform calculations involving the relationship between the wavelength and frequency of electromagnetic radiation, v=λf\begin{align*}v = \lambda f\end{align*}.
• perform calculations involving the relationship between the energy and the frequency of electromagnetic radiation, E=hf\begin{align*}E = hf\end{align*}.
• state the velocity of electromagnetic radiation in a vacuum.
• name at least three different areas of the electromagnetic spectrum.
• when given two comparative colors or areas in the electromagnetic spectrum, identify which area has the higher wavelength, the higher frequency, and the higher energy.
