Question

Light from a phosphorescent source:

a. takes longer to travel from the source to you
b. normally has a shorter wavelength than the light that initially produced it
c. is cooler than light from a florescent source
d. all of these
e. none of these

Answer 1

Phosphorescence is the process of light emission that occurs after the absorption of photons by a material and it differs from fluorescence in that the emission of light in phosphorescence takes longer to occur.

Step-by-step explanation:

Phosphorescence is the process of light emission that occurs after the absorption of photons by a material. It differs from fluorescence in that the emission of light in phosphorescence takes longer to occur. This is because in phosphorescence, the absorbed energy is stored in excited states for a longer period before being emitted as light, while in fluorescence, the emission happens almost immediately after the absorption.
