The correct answer is:

✅ UVC

UVC has the shortest wavelength (100–280 nm) and highest energy among UV types.

Key Fact: It’s almost entirely absorbed by the ozone layer and doesn’t reach Earth’s surface.

UVB (280–315 nm): Longer than UVC; causes sunburns/skin cancer.

UVA (315–400 nm): Longest UV wavelength; penetrates deep into skin (aging, wrinkles).

Fun Fact: UVC is used in germicidal lamps to sterilize surfaces—it kills microbes! 🦠💡

Safety Note: Artificial UVC sources (e.g., mercury lamps) require caution—never expose skin/eyes! ⚠️👁️
