Continuous/Line and Absorption/Emssion spectrum... There are indeed
emission continuous spectrum... coloured spectrum (e.g. sun)
absorption continuous spectrum... coloured background with dim(dark) lines
emssion line spectrum... line spectrum (discharge tube)
absorption line spectrum... line spectrum, some dimmer or even disappear
How line spectrum verifies discrete energy levels?
E.M. wave is emitted due to electron transition between energy levels while E = hf.
Each line in a line spectrum corresponds to a specific frequency, and hence energy E.
Line spectrum is the result of discrete energy change between energy levels of atom.
So, the energy levels of atom are discrete.
