How do UVB rays affect the skin differently from UVA rays?

  1. They penetrate less deeply but cause more immediate damage

  2. They are safer and used in medical treatments

  3. They have no effect on the skin

  4. They penetrate more deeply and cause long-term damage

The correct answer is: They penetrate less deeply but cause more immediate damage

UVB rays are shorter wavelengths and penetrate less deeply into the skin compared to UVA rays. While they don't penetrate as deeply, they can still cause more immediate and visible damage such as sunburn. UVA rays on the other hand, penetrate more deeply and can cause long-term damage like premature aging and skin cancer. B and C are incorrect because both types of UV rays can be harmful to the skin. D is incorrect because it describes the effects of UVA rays, not UVB rays.
