Electromagnetic Spectrum - Slides 5-6 What is the EM Spectrum? List the waves in order from lowest frequency to highest frequency. REMEMBER: low frequency=low energy and high frequency=high energy As frequency increases what happens to wavelength?

The electromagnetic spectrum (EM Spectrum) is the range of all types of electromagnetic radiation, which varies from very long radio waves to very short gamma rays. Each part of the spectrum serves different purposes, from communication to medical imaging. The fundamental principle here is that all these waves travel at the speed of light but differ in their frequencies and wavelengths. Starting from the lowest frequency to the highest, the waves are arranged as follows: radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays. As frequency increases, the wavelength decreases – meaning that high-frequency waves have shorter wavelengths, while low-frequency waves have longer wavelengths. It's like a party: low frequencies have space to dance, but as the beats get higher, everyone has to get closer together!
