Describe the speed of all light waves
WebThe speed of a wave is determined by multiplying the _____of the wave by its wavelength. In a vacuum all electromagnetic radiation travels at a constant speed, the … WebElectromagnetic radiation consists of energised particles creating waves of energy with no mass (particle-like behaviour). Electromagnetic waves travel at the same speed in a vacuum, which is the same speed as the speed of light (3 ⋅ 10 8 m/s). Electromagnetic waves can travel in a vacuum; therefore, they don ’ t need a medium to transmit.
