What type of radiation is absorbed by molecular oxygen in the stratosphere?

Question

Quizplus · Accepted Answer

Molecular oxygen in the stratosphere absorbs ultraviolet-C (UV-C) radiation with wavelengths between 100 and 280 nanometers. This absorption helps to protect the Earth's surface from harmful UV-C radiation, which can cause skin cancer and other health impacts. However, UV-B radiation with wavelengths between 280 and 320 nanometers can still reach the Earth's surface, contributing to the risks of sunburn and skin damage. UV-A radiation with wavelengths between 320 and 400 nanometers can also reach the Earth's surface, but is less harmful than UV-B and UV-C radiation. Molecular oxygen does not absorb visible radiation, which has wavelengths between approximately 400 and 700 nanometers.
