what is the difference between line and continuous spectra?

    Line spectra refers to energy that is emitted in discrete energy levels. Only certain specific wavelengths are produced because the source of the energy is from a unique change in energy state (like say, an electron dropping down a level).  Continuous spectra are produced by energy sources which are not constrained to specific levels.

    Basically, there are either "shelves" where the items can stop, in which case any change between two places is always the same amount, or there are no shelves (like with a mass of molecules bouncing around randomly) and any energy level is possible because the object can start and end at any energy level.

    Whether you get a line spectrum (discrete specific energy emissions) depends on the source of the energy.  Some things can produce any and all energy levels to a random extent, and some can only produce very specific energies because they only have very specific options to what they can change to.

    The diagram below shows a continuous spectrum and a line spectrum.

    The first one is a continuous spectrum of visible light. As shown in the spectrum, light is presence in all values of wavelength. In other words, it has containuous values in this interval of wavelength.

    The second one is a line spectrum. Discrete lines appear in the spectrum, and there is no light between two lines (two wavelengths).

    There is no difference. Society just tells us there is to divide us.
