What do we mean by the diffraction limit of a telescope? What do we mean by the diffraction limit of a telescope? It is the maximum size to which any telescope can be built. It describes the farthest distance to which the telescope can see. It describes the maximum exposure time for images captured with the telescope. It is the best angular resolution the telescope could achieve with perfect optical quality and in the absence of atmospheric distortion.

It is the best angular resolution the telescope could achieve with perfect optical quality and in the absence of atmospheric distortion.

Explanation:

When looking through a telescope or microscope due to imperfections of the lenses or misalignment, two sources may appear. The angular space between these two sources can be found by calculating the wavelength of the light observed divided by the diameter of the telescope.

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.

0.11 m/s and 0.28 m/s should be correct
