Question

which type of uv radiation is the most damaging and is completely filtered out by the ozone layer? uv - c uv - a

Explanation:

UV - C radiation has the shortest wavelength among UV radiations. Due to its high energy (energy is inversely proportional to wavelength for electromagnetic radiation, \(E=\frac{hc}{\lambda}\), where \(h\) is Planck's constant, \(c\) is the speed of light, and \(\lambda\) is the wavelength), it is the most damaging. The ozone layer (\(O_3\)) effectively absorbs UV - C radiation through chemical reactions. For example, \(O_3\) can absorb UV - C photons and break down into \(O_2\) and \(O\) atoms, preventing UV - C from reaching the Earth's surface.

Answer:

UV - C
