Question 1

The principle of superposition states:

Accepted Answer

A) The effect observed at each point of a wave made up of two or more waves is the sum of the effects that the individual waves would produce at that point. 
B) Huygens' wavelets cannot be allowed to extend across regions where the phase velocity of the wave changes abruptly. 
C) Sources of radiation whose phase angles are maintained at constant differences are said to be coherent. 
D) A characteristic phenomenon of wave propagation is the tendency of a wave to expand around and behind any obstacles it chances to encounter. 
E) A good source of waves at a particular frequency is a good detector of waves at the same frequency.
