Module 5—Wave Theory of Light

Module Introduction

 

In Physics 20 you examined the properties of waves and the universal wave equation: c = fλ. In Physics 30: Unit B you examined how changing electric fields and magnetic fields can induce each other. In Module 5 you will expand upon your understanding of waves and electric and magnetic fields to see how they form waves of electromagnetic radiation (EMR).

 

In Module 5 you will explore the wave nature of EMR. You will do this by looking at the electromagnetic spectrum, including visible light, and how EMR properties change as the frequency or wavelength changes. You will study the properties of EMR, reflection, refraction, and diffraction, and evaluate how each property shows evidence of the wave nature of EMR. Along the way you will look at the work of James Clerk Maxwell, who established the theory of the wave nature of EMR. You will also study Heinrich Hertz, who performed the experiments that led to an understanding of EMR. Finally, you will see how experimentation developed to accurately measure the speed of light.
