Alex has a type of rock called calcite, that sometimes glows. He puts the calcite under a desk lamp but the calcite does not glow. Then he puts it under an ultraviolet lamp and the calcite glows. Why does ultraviolet light make the calcite glow when light from the desk lamp does not? * 1 point

Explanation:

The ultraviolet light is responsible for the glow. It activate the calcite and causes it to temporarily emit visible light of various colors. This light emission is known as "fluorescence."

Calcite has the ability to temporarily absorb a small amount of light and an instant later release a small amount of light of a different wavelength. This change in wavelength causes a temporary color change of the mineral in the eye of a human observer.

This process of flourescence occurs when a specimen is illuminated with specific wavelengths of light. Ultraviolet (UV) light, x-rays, and cathode rays are several examples of light that can cause this process. The light from the desk is not enough to cause thsi flourescence.
