Electromagnetic Spectrum


The other week my softball team had a team bonding. Part of the team bonding we had a little scavanger hunt where we took pictures with random things and people. I think one of the pictures we had to get was with a rainbow. I realized that the colors found in the rainbow are part of physics because it is part of the electromagnetic spectrum. This spectrum is types of electromagnetic radiation organized by it frequency or wavelength, which each have their own electric and magnetic field. In the spectrum, it includes radio waves, infared, UV, x-rays, gamma rays, and visible light. The visible light is what consists of the rainbow because visible light includes all the colors and white. In the electromagnetic spectrum, as you move to the right of the chart, the frequency of the wave increases as the wavelength decreases. Meaning that the frequency and wavelength vary inversely.
