Question

Which statement best describes the difference between ultraviolet light and infrared light?

Answer 1

While both are on the high frequency end of the spectrum, ultraviolet has the higher frequency.
Infrared radiation has a lower frequency and less radiant energy so when it interacts with matter, it causes the molecules to vibrate and result in heat emission.
On the other hand ultraviolet radiation possesses a higher frequency and higher radiant energy therefore when molecules in matter are exposed to UV they collide more violently sometimes causing a change in its atomic or molecular structure and ultimately its chemical composition.

Answer 2

Your answer should be the second choice. While both are on the high frequency end of the spectrum, ultraviolet has the higher frequency.
Hope this helps!
