In a vacuum, all electromagnetic waves travel at approximately 3 x 108 m/s - the fastest speed possible. When electromagnetic waves travel through matter (for example, light through air or glass), they travel a bit slower than this but rarely less than half as fast as in a vacuum. The value for light travelling through an optical fibre, for example, is taken as 2 x 108 m/s.
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).
