| The figure to the right shows a
schematic diagram of a meterstick spectroscope. To use the spectroscope,
drag the eye of the observer until it lines up
with an emission line. Geometry labels and the
diffraction equation will appear.
Move the
observer to different lines to see how wavelength
changes with angle. Notice how the spectrum on
the meterstick changes with the viewing angle.
To examine the
spectra of different elements, change the light
source.
