1. The argument was as follows: If light consists of corpuscles which bounce like tennis balls off of a surface, why so some particles then enter the water? Note that the theory was not accepted by Newton's contemporaries because it could not explain certain aspects of the behaviour of light, not because it was wrong.

2. This is a figurative was of saying that the water did not allow the next corpuscle or some of the corpuscles to pass through.

3. Wave mechanics study of radiation in the form of particles (quanta) which travel in waves. It combines the wave theory of light with the particle ("corpuscular") theory.
