How do the values of photon energy help explain warnings about sunburn?

Photon energy is directly related to the frequency of ultraviolet (UV) light emitted by the sun. Higher-energy photons, particularly in the UV spectrum, have the ability to penetrate skin cells and can cause damage to DNA, leading to sunburns and increasing the risk of skin cancer. Warnings about sunburn are based on the understanding that exposure to high-energy UV radiation can result in harmful effects, emphasizing the need for protective measures like sunscreen and clothing.
