WebAll EM energy waves travel at the speed of light. No matter what their frequency or wavelength, they always move at the same speed. Some properties of waves, such as diffraction and interference, are also seen in EM radiation. Scientists have figured out that there are tiny particles in these waves; they are called photons. WebUV radiation is the portion of the EM spectrum between X-rays and visible light. More Information on UV Radiation Q: How is radiation classified on the electromagnetic … 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. biomat clearfield utah
