There is no essential difference in the nature of gamma rays and green light other than he difference in frequency and wavelength. C. Greenlight undergoes refraction, gamma rays I do not D. Gamma rays are a form of radiation, green light is not E. Greenlight is the beam of photons, gamma rays are not photons

We use sunscreen to protect ourselves from the UV rays of the sun or a "lead coat"to protect ourselves from s-rays, but we do not protect ourselves when standing in front of a microwave. why is it that UV and X rays are harmful to life but microwaves arent
