... (b) Recall that for a beam of free particles, ψ ∗ (x)ψ(x) gives the number of particles per unit distance. Using this, discuss whether it would be possible to find a particle in the region x > 0 if a measurement were made on the system. (c) What is the probability that an incident particle will be r ...

... Max Planck solved the problem mathematically (in 1900) by assuming that the light can only be released in “chunks” of a discrete size (quantized like currency or the notes on a piano). l = wavelength (m) We can think of these “chunks” as n = frequency (s-1) particles of light called photons. h = Pla ...
