We spend our lives in visible light without risks to our health. yet exposure to uv waves in sunlight can cause skin cancer. what is the best explanation for this?
a. uv waves are longer and carry more energy.
b. uv waves are higher frequency and carry more energy.
c. uv waves have a lower frequency and carry more energy.
d. uv waves travel faster than visible light and have more energy.

Uv waves have a higher ionization potential as they have a higher frequency and carry more energy.

An  atom  (ours, not carroll's) consists of a positively charged  nucleus, surrounded by one or more negatively charged particles called  electrons. the positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. most of an atom's mass is in its nucleus; the mass of an electron is only 1/1836 the mass of the lightest nucleus, that of hydrogen. although the nucleus is heavy, it is quite small compared with the overall size of an atom. the radius of a typical atom is around 0.1 to 0.25 nanometres (nm), whereas the radius of a nucleus is about 10-6  nm.  *  if an atom were enlarged to the size of the earth, its nucleus would be only 200 feet in diameter and could easily rest inside a small football stadium.read more on -
