Which of the following is a characteristic of UVA rays?

UVA rays are known for their ability to penetrate deeper into the skin compared to other types of ultraviolet rays, specifically UVB rays. This deeper penetration can lead to long-term skin damage, such as photoaging and an increased risk of skin cancer. UVA rays are prevalent throughout the year and can even penetrate through clouds and window glass, which contributes to their ubiquitous presence in environments where people may think they are shielded from UV exposure.

The characteristic of UVA rays penetrating deeper into the skin highlights the importance of using broad-spectrum sunscreen, which protects against both UVA and UVB rays. A better understanding of UVA rays and their effects can help in advocating for appropriate sun protection measures.
