In which of the following cases does absorbance and fluorescence occur: a) a molecule returns to the ground state electron from a triplet excited state losing its extra energy with the photon radiation
b) a molecule returns to the ground state electron from a single excited state losing its extra energy with the photon radiation
c) a molecule passes to a lower oscillating level losing its additional energy
d) absorbs energy
e) absorbs adequate energy by switching from the ground state S0 to an excited state

explain the answer

freezing

deposition

condensation

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.

diagram is missing, but i will try to explain your doubt.

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.
