Question
There are two categories of ultraviolet light.
Ultraviolet A (UVA) has a wavelength ranging from
320 nm to 400 nm. It is necessary for the
production of vitamin D. UVB, with a wavelength in
vacuum between 280 nm and 320 nm, is more
dangerous because it is much more likely to cause
skin cancer.
