WebUnlike higher frequency waves such as infrared and visible light which are absorbed mainly at surfaces, microwaves can penetrate into materials and deposit their energy below the surface. This effect is used to heat food in microwave ovens, and for industrial heating and medical diathermy. WebHigher-energy UV rays are a form of ionizing radiation. This means they have enough energy to remove an electron from (ionize) an atom or molecule. Ionizing radiation can damage the DNA (genes) in cells, which in turn may lead to cancer. Web1 de abr. de 2024 · Ultraviolet radiation lies between wavelengths of about 400 nanometres (1 nanometre [nm] is 10 −9 metre) on the visible-light side and about 10 nm on the X-ray side, though some authorities extend the … correctional officers attacked by inmates
