Bohr's Study of Spectra
When white light is passed through a glass prism → broken up into an array of colours → continuous spectrum
Bohr used a hydrogen discharge tube instead of white light
Hydrogen discharge tube: glass tube filled with hydrogen gas at low pressure through with an electric current is passed
Instead of a continuous spectrum he saw a series of narrow coloured lines → emission line spectrum
When light emitted by other elements were studied they also produces its own unique spectrum
Spectrometer: used to carry out measurements on spectra
Spectroscope: used to observe specrta
