The Secrets of Electromagnetic Radiation and Its Colorful Impact

Mr. Anderson's video on electromagnetic radiation covers the historical discovery of infrared rays by William Herschel and explains the electromagnetic spectrum, including visible light, gamma rays, and radio waves. The video discusses the inverse relationship between wavelength and frequency, and how energy increases with frequency. It also highlights the practical implications and safety concerns of exposure to different types of electromagnetic radiation.

What did Newton demonstrate with a prism and white light?

• White light remains unchanged when passed through a prism.

• White light is split into different colors by a prism.
