Dangers of microwaves gcse physics
WebElectromagnetic (EM) waves carry energy and so can transfer energy from one point to another point. EM radiation is an energy transfer pathway. EM waves with a shorter wavelength carry a higher energy. This includes UV, X-rays and gamma rays. The higher the energy of the EM wave, the more dangerous it is.
