The skin and eyes are most sensitive to damage by UV at 265–275 nm , which is in the lower UV‑C band. At still shorter wavelengths of UV, damage continues to happen, but the overt effects are not as great with so little penetrating the atmosphere.
Read moreIs a millimeter wave a microwave?
Millimeter waves are electromagnetic (radio) waves typically defined to lie within the frequency range of 30–300 GHz. The microwave band is just below the millimeter-wave band and is typically defined to cover the 3–30-GHz range .
