What is a type of cold light that is blocked by the ozone layer?

Explanation:
The key idea is how the ozone layer filters ultraviolet radiation. Among ultraviolet wavelengths, UVC has the shortest wavelengths and the most energy, so the ozone layer absorbs it very effectively. This means UVC is blocked before it ever reaches the Earth's surface. In contrast, UVA is less affected and mostly gets through, UVB is largely absorbed but some can reach the surface, and visible light is not ultraviolet and passes through the atmosphere with little blockage.
