ช่วงคลื่นที่ตามองเห็น Visible Radia

The visible spectrum range, Visible Radiation is 400-760 nm wavelength.Will be able to log in to the skin of a human being, but it will not absorb it so it does not harm the human body, but the nest color, ultra violet (UVA), and b (UVB)-can enter into the skin and absorb UVA rays enter into the skin deep and absorb more than UVB rays?

The visible spectrum is Visible Radiation wavelength 400 - 760 nm
can enter the skin of humans. But it is not absorbed and therefore not harmful to the human body. But rays, ultra-violet A and B (UVA), (UVB) can enter the skin. And UVA rays are absorbed by the skin deep. And absorb more UVB radiation
