IB Physics: 12.1 Quantum physics

We know that low pressure gases only emit light of specific wavelengths that form a line spectrum. This leads us to believe that electrons only exist in certain discrete energy levels. We say electron energy is quantized: it can only have certain values.This is not something that would be predicted by classical mechanics. In a box full of bouncing balls each ball could have any energy ranging from zero to the total energy...
