What are speeds of sound and of light . We are doing research on lightning and thunder . The speed of sound through air is about 340 meters per second. (The speed of sound in water is about 4 times faster than this). The speed of light in air is about 300 million meters per second.
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.
