Based on this information, which type of light might cause the glass to melt?

• The infrared light can cause the glass to melt.

• The yellow light can cause the glass to melt.

• The X-ray light can cause the glass to melt.The X-ray light can cause the glass to melt.

• Any of these types of light can cause the glass to melt, because all light carries energy that can cause materials to change.
