1) why do atoms have discrete spectral lines?
2) Is it possible for different atomic transitions, in a
particular atom, to give off the same colour photons?why?
3) A beam of red photons and blue photons are sent through a
diffraction grating simultaneously. Sketch the diffraction pattern
of both colours.
4) The spectrometer provided is able to measure angles to a
precision of 1 minute (1'). Given that 60'=1degree, convert the
following angles, 31degree 21' and 12degree 5', into degrees.
