In this lesson on Light and the Electromagnetic Spectrum, which is part of Unit 4 Area of Study 1 for VCE Physics, you’ll learn how to:
- describe light as an electromagnetic wave which is produced by the acceleration of charges, which in turn produces changing electric fields and associated changing magnetic fields
- identify that all electromagnetic waves travel at the same speed, c, in a vacuum
- compare the wavelength and frequencies of different regions of the electromagnetic spectrum, including radio, microwave, infrared, visible, ultraviolet, x-ray and gamma, and identify the distinct uses each has in society.
What is Light?
Uses of Electromagnetic Waves
This video will look at the uses of the electromagnetic waves and explain the reasons why each wave is suited to its uses.
Unification of electricity and magnetism
Prediction of electromagnetic waves
Prediction of velocity
