Distinguish between fluorescence and phosphorescence.

Question 2

In Figure OQ32.4, the switch is left in position a for a long time interval and is then quickly thrown to position b. Rank the magnitudes of the voltages across the four circuit elements a short time thereafter from the largest to the smallest.
 
  1.VL > V1200  > 12.0 V > V12
  2.V1200  > VL > 12.0 V > V12
  3.VL > V12  > 12.0 V > V1200  
  4.12.0 V > VL > V12  >  V1200
  5.V12  > 12.0 V > V1200  >  VL
  6.None of the above

Fluorescence is the immediate emission of radiation, such as visible light, produced
by the absorption of other radiation of a higher frequency. Phosphorescence is the
persistent emission of light following exposure to and removal of incident radiation
from the sample.
