Question 12 • (AG Q3) Physical Science: 25-26 (JComunale)

A museum sets up a display of fluorescent minerals. Which best describes how electromagnetic waves can be used to enhance the display?

Answer

A

Infrared light shining on the minerals will cause them to give off visible light.

B

Visible light shining on the minerals will cause them to give off infrared light.

C

Ultraviolet light shining on the minerals will cause them to give off visible light.

D

Visible light shining on the minerals will cause them to give off ultraviolet light.

Explanation

Fluorescent minerals absorb higher-energy ultraviolet light and then release some of that energy as lower-energy visible light. Shining ultraviolet light on the minerals can therefore make them glow visibly, which is the effect described by choice C. Infrared light has less energy than visible light, so it does not fit this process.
