Which of the following best explains why ultraviolet rays can cause sunburn but visible light from a light bulb does not damage skin?

• Ultraviolet rays come before the light rays in the electromagnetic spectrum, which means anything before visible light automatically causes cancer.

• Ultraviolet rays have lower frequencies than visible light rays and thus have higher energy than light rays from a light bulb.

• Ultraviolet rays have higher frequency than visible light rays and thus have more energy than light rays from a light bulb.

• Ultraviolet rays have higher frequencies than visible light rays and thus have less energy than light rays from a light bulb.
