This physics and chemistry video tutorial focuses on the electromagnetic spectrum. It discusses the relationship between wavelength, energy, and frequency among the different types of EM waves such as radiowaves, microwaves, infrared, visible light, ultraviolet radiation, xrays, gamma rays, and cosmic radiation. This video includes plenty of examples and math practice problems.

Here is a list of topics:
1. EM spectrum Electromagnetic Radiation
