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, x-rays, 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
2. Relationship between wavelength, frequency, and energy
3. Ranking Waves In Order of Increasing Frequency and Energy - Lowest to Highest
4. EM Waves - In Order of Decreasing Wavelength - Longest to Shortest
5. Visible Light Spectrum - ROYGBIV
6. Speed of Light, Frequency, Wavelength Equation / Formula
7. Calculating the Energy of a Photon Given Wavelength in nm
8. Joules to Electron Volts - eV Unit Conversion
9. Planck's Constant - h
10. Direct Relationship - Energy and Frequency
11. Inverse Relationship - Wavelength and Frequency
12. Speed of Light in Water - Index of Refraction
