The power point covers the electromagnetic spectrum, light, photons, waves and their characteristics. the relationship between frequency, wavelength, and the speed of light are introduced with the formula for speed of light.
Calculating the energy of the electromagnetic waves is also covered with introduction to Planck's constant and the energy formula derived using the constant. How we see light is presented along with slides for each type of electromagnetic ray and how they can affect human health. I also have a slide on cosmic rays since they have the most energy of all electromagnetic rays.
Here is a problem set to follow up the power point Visible Light Spectrum: Speed of Light, Planck's Constant, Energy of Light
Here is are two accompanying foldables:
