Electromagnetic Radiation

Mr. Anderson explains electromagnetic radiation, starting with Herschel's experiment that discovered infrared rays. He describes the electromagnetic spectrum, highlighting the relationship between wavelength, frequency, and energy. The video covers practical examples of electromagnetic waves, their scale, and the inverse relationship between wavelength and frequency. Safety considerations regarding exposure to different types of radiation are also discussed.

How does the experiment conducted by Herschel relate to the concept of visible light?

Why is it important to understand the differences in energy levels of electromagnetic radiation?
