WebIt is for this reason that we wear suntan lotion at the beach (to block the UV rays from the sun) and why an X-ray technician will place a lead shield over us, in order to prevent the X-rays from penetrating anything other than the area of our body being imaged. Gamma rays, being the highest in frequency and energy, are the most damaging. WebUV and IR - Key takeaways. Ultraviolet (UV) radiation is electromagnetic radiation between the violet part of visible light and X-rays on the EM spectrum. UV radiation has wavelengths between 100-380nm and is emitted from the sun's surface. Infrared (IR) radiation is between the red part of visible light and microwaves on the EM spectrum. WebDepending on the frequency of the electromagnetic radiation, chemists can probe different parts of an atom or molecule's structure using different kinds of spectroscopy.
