Electromagnetic waves

This page covers the following topics:

1. Basics of electromagnetic waves
2. The Electromagnetic Spectrum

Electromagnetic waves are transverse waves, so particles move perpendicular to the direction of energy transfer. Their oscillations are changes in electrical and magnetic fields which are in phase with each other and vibrate at 90Β° from each other.

Basics of electromagnetic waves

Electromagnetic waves run along a spectrum of different wavelengths. All of these waves travel at the same speed in a vacuum, but the different frequencies and wavelengths means that each of the various waves on the spectrum have different properties.

The Electromagnetic Spectrum

1

The human eye is only able to see a small range of wavelengths within the electromagnetic spectrum. How does the eye experience these different wavelengths in the visible light part of the spectrum?
