Interpretation : The energy of the photons absorbed by the electrons in glow-in-the-dark objects is to be calculated.
Concept Introduction : Planck demonstrated mathematically that a body's ability to absorb or emit radiation is inversely related to the frequency of the radiation (v). The formula of energy is given as:
Where
Answer to Problem 88A
