1: Which UV light is typically most harmfull for human skin outside, at sea level during the day?
UV-A (315 - 400 nm)
UV-B (280 - 315 nm)
UV-C (100 - 280 nm)
1: How is UV light classified into A, B and C?
Based on their energy rations relativ to IR light
Based on their biological effect
Based on their chemical effect
Based on their ozone generating effect
