Which type of UV radiation has longer wavelengths and penetrates deeper into the skin?

UVA
UVC
Infrared
Visible Light

The correct answer is: UVA

UVA radiation has longer wavelengths compared to UVB and UVC, allowing it to penetrate deeper into the skin. This deeper penetration can lead to skin aging, wrinkling, and potential DNA damage, making UVA exposure a significant concern in skincare. In contrast, UVB primarily affects the outer layer of the skin and is responsible for sunburns, while UVC is mostly absorbed by the atmosphere and does not reach the Earth's surface in significant amounts. Infrared and visible light do not have the same wavelength characteristics as UVA and do not penetrate the skin as deeply as UVA radiation.
