Question 8 • *26-27 CFISD TX-Chemistry A CR

This flow chart shows the amount of energy that is emitted by each type of light. ultraviolet > blue light > yellow light > red light (maximum energy) (minimum energy)In an experiment, shining which type of light on a strip of metal would be least likely to produce the photoelectric effect?

Answer
A
ultraviolet light
B
dim blue light
C
bright red light
D
bright yellow light

Explanation

The photoelectric effect occurs when individual light photons have enough energy to eject electrons from the metal. The chart shows that red light has the least energy per photon, so bright red light is least likely to cause the effect. Brightness increases the number of photons, but it does not increase the energy of each photon.
