Flashlight em waves

WebElectromagnetic radiation consists of energised particles creating waves of energy with no mass (particle-like behaviour). Electromagnetic waves travel at the same speed in a vacuum, which is the same speed as the speed of light (3 ⋅ 10 8 m/s). Electromagnetic waves can travel in a vacuum; therefore, they don ’ t need a medium to transmit. In physics, electromagnetic radiation (EMR) consists of waves of the electromagnetic (EM) field, which propagate through space and carry momentum and electromagnetic radiant energy. Types of EMR include radio waves, microwaves, infrared, (visible) light, ultraviolet, X-rays, and gamma rays, all of which are part of the electromagnetic spectrum.
