Question

paintings in museums have to be kept away from ultraviolet light. ultraviolet light will cause the paint to fade, but the overhead lamps in a museum won’t cause the paint to fade. why does the ultraviolet light cause the paint to fade when light from the overhead lamps does not? because ultraviolet light pulls energy out of the paint, and light from the overhead lamps does not. because ultraviolet light carries energy, and light from the overhead lamps does not. because the paint can take in energy from ultraviolet light but not from the light from the overhead lamps. because ultraviolet light carries heat molecules, and light from the overhead lamps does not.

Explanation:

1. Analyze Option 1: Light doesn't "pull" energy from paint; it transfers energy when absorbed, so this is incorrect.
2. Analyze Option 2: All light carries energy (electromagnetic radiation), so overhead lamps also carry energy. This is wrong.
3. Analyze Option 3: Paint fades when it absorbs energy that causes chemical changes. Ultraviolet light has enough energy to cause these changes, while the light from overhead lamps (likely visible light) may not be absorbed in a way that causes fading. This makes sense.
4. Analyze Option 4: Light doesn't carry "heat molecules"—heat transfer related to light is via energy (radiation), not molecules. This is incorrect.

Answer:

C. Because the paint can take in energy from ultraviolet light but not from the light from the overhead lamps. (Assuming the options are labeled A, B, C, D with C being the third option as per the analysis)
