All electromagnetic radiation travels at the same speed (in a vacuum). Electromagnetic radiation travels very quickly. There is nothing which can travel faster. The speed is 300,000,000 m/s in a vacuum (that is 300 million metres per second-not easy to imagine!). Electromagnetic radiation can be thought of as particles or waves (the word radiation is also used for radioactivity).
Yes and No...electromagnetic waves travel at different speeds in different mediums, however in a vacuum all electromagnetic waves travel at c (3*10^8 m/s) or 186,000 miles per â¦ second i believe :P. Scientists created a scalar called the index of refraction for materials that refract light such as glass and water.
