(c) Newton considered light as made up of particle called corpuscles. The corpuscles of light were assumed to be almost point like particles without any mass. They travel with a tremendously high speed, so they experience a negligible force of gravity. As a result, the corpuscles travel in a straight line. |
In the interference pattern, energy is |
|||
a) |
Created at the position of maxima |
b) |
Destroyed at the position of minima |
c) |
Conserved but is redistributed |
d) |
None of the above |
