| Objective | ||
| In this lesson the focus shifts from sound as an example of wave motion to light, and electromagnetic radiation in general, as another example of a wave phenomenon. This lesson will focus on how we have come to know that light is a transverse electromagnetic wave that travels at a finite speed without the need for a medium starting with early theories of light and leading to Maxwell's theory and Hertz's demonstration. | ||
| Prescribed Focus Area | Skills Development | Content |
P1 A student outlines the historical development of major principles, concepts and ideas in physics. |
P12.3 Students gather information from secondary sources |
D1.3 Students learn to identify that mechanical waves require a medium for propagation while electromagnetic waves do not |
| Activity | Resources | Homework |
|
Write a short essay, use the Internet as a source, on how light was discovered to be a transverse electromagnetic wave. |
