Spectroscope
Description
Hand held simplest form of spectroscope. It can be used to get a general idea of the correlation between wavelength and observed color. A diffraction grating is used which spreads the incident light into its component wavelengths. An illuminated reference scale against which the spectrum may be viewed is also provided.
