If you are driving an oscillatory system at a certain frequency, but the amplitude is much smaller than it could be, you can be certain that

1. the driving frequency is too low.
2. the driving frequency is too high.
3. the driving frequency is not matched to the natural frequency of the oscillatory system.

3. The driving frequency is not matched to the natural frequency of the oscillatory system.

Explanation:

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.
