Which rays are known to cause skin cancer?

UVA rays
UVB rays
UVC rays
Infrared rays

The correct answer is: UVB rays

UVB rays are known to cause skin cancer, primarily because they have a high energy level that can penetrate the outer layers of the skin and cause direct damage to the DNA within skin cells. This damage is a significant factor in the development of skin cancers, particularly melanoma, which is the most serious type of skin cancer. UVB rays are most intense during midday and in the summer, making it important for individuals to protect their skin during these times. Sunscreens that block UVB rays are crucial for reducing the risk of skin cancer, and protective measures like wearing clothing or seeking shade can help mitigate potential exposure. UVA rays do contribute to skin aging and can damage the skin as well, but their primary role is in the formation of wrinkles and skin texture issues, rather than directly causing skin cancer. UVC rays are mostly absorbed by the Earth’s atmosphere and do not typically reach the ground, making them less relevant to skin cancer risk. Infrared rays, while they can affect the skin, primarily cause heat and are not known to be a cause of skin cancer.
