[Solved] Why do all electromagnetic waves travel at the same speed
WebIn empty space, all colors travel at the same speed called c. Light of different wavelengths, or colours, travels at different speeds when they travel through any medium other than vacuum. That last statement is not exactly true but the reasons are complicated and you can just look up solitons. Red light travels faster than blue in glass. Share Webtravel at the same speed through a vacuum or the air ; Electromagnetic waves travel at 300,000,000 metres per second (m/s) through a vacuum. Electromagnetic spectrum. … WebAnswer (1 of 5): yes they are electromagnetic waves just like light - the semantics are a bit tricky here but basically - they ARE light - light radiowaves gammarays, radar, microwaves, x-rays, infrared, ultraviolet and even just a very slowly changing electromagnetic field causing a low freuqenc... picket on spectrum
