What are X-rays? X-rays are a part of the Electromagnetic (EM) spectrum, which means that they are transverse waves having a certain wavelength and frequency and moving at the speed of light. In the EM spectrum, we have gamma rays, x-rays, ultraviolet rays, visible light, infrared waves, microwaves, and radio

Introduction to Electromagnetic waves and electromagnetic spectrum Waves are categorized into three main types, mechanical , electromagnetic , and matter waves. The waves that can pass through a medium are called mechanical waves. Whereas, electromagnetic waves (EM Waves), a special type of wave, do not require a medium to travel
