lan wonders if sunscreen lotion will dry out if it is exposed to light. The table below shows what happens when different types of light hit the sunscreen
Based on this information, which type of light is more likely to dry out the sunscreen?

a
The ultraviolet light is more likely to dry out the sunscreen because the ultraviolet light bounces off of the sunscreen, which means that it has more energy.

b
The X-ray light is more likely to dry out the sunscreen because the X-ray light can pull energy out of the sunscreen when it passes through the sunscreen.


c
There is no way to know because they are two different types of light, and different types of light can change material in different ways.


d
Neither type of light is likely to dry out the sunscreen because the sunscreen does not take in energy from either the ultraviolet light or the X-ray light.
