1 In a vacuum, all electromagnetic waves travel at approximately 3 x 10 8 m/s-the fastest speed possible. 2  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.
Wave speed is the speed at which a wave travels. Wave speed is related to wavelength, frequency, and period by the equation wave speed = frequency x wavelength. The most commonly used wave speed is the speed of visible light, an electromagnetic wave. wave speed. Alright. Let's talk about wave speed.
