How em waves travel
Web16 jul. 2024 · Ergo, light is made of electromagnetic waves and it travels at that speed, because that is exactly how quickly waves of electricity and magnetism travel through … WebDo radio waves travel forever? In theory, an EM wave can travel indefinitely. Because they don’t need a medium, electromagnetic waves can pass through outer space, which is a quasi-vacuum. Moreover, because they don’t give up energy as they move, electromagnetic waves can travel the great distances between stars and galaxies.

Examples include gamma rays, X-rays, ultraviolet waves, visible light, infrared waves, microwaves, and radio waves. Electromagnetic waves can travel through a vacuum at the speed of light, v = c = 2.99792458 × 10 8 m/s. v = c = 2 ...
Mechanical waves and electromagnetic waves are two important ways that energy is transported in the world around us. Waves in water and sound waves in air are two examples of mechanical waves. Mechanical waves are caused by a disturbance or vibration in matter, whether solid, gas, liquid, or plasma.
