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.
On the electromagnetic spectrum, radio waves are found on the end of the spectrum considered to possess a low amount of energy. Which statement most accurately describes the wavelength/frequency relationship present in radio waves?

Why does this apple look red?
The apple reflects red light and absorbs all other colors
The apple absorbs red light and reflects all other colors
The apple reflects all the light shinning on it
The apple is red because we see that color.
