Electromagnetism. Ultraviolet radiation with wavelengths between 280-320 nm. UVB induces the production of vitamin D in the skin. An overexposure to UVB can cause sunburn and some forms of skin cancer. UVB can cause direct DNA damage by inducing aberrant covalent bonds to form between adjacent cytosine bases, producing a dimer. Exposure to UVB light is an effective long-term treatment for many skin conditions like eczema.
