Some minerals glow when illuminated with ultraviolet light.This is because
A)ultraviolet photons kick atomic electrons in the mineral into higher energy states.
B)ultraviolet photons have such high energy.
C)of selective reflection.
D)of selective transmission.
E)none of these

Question

Quizplus · Accepted Answer

Ultraviolet photons have enough energy to excite atomic electrons in the mineral to higher energy levels. When these electrons return to their original energy states, they release excess energy in the form of visible light, causing the mineral to glow. This phenomenon is known as fluorescence.
