Spectra of re ected sunlight from Mars and Jupiter are presented. They were obtained from an educational 1-D array spectrograph covering almost a full range of visible wavelengths, 200 ~ 900 nm with 1 nm spectral resolution. The question was whether a spectral difference could be obtained between that of terrestrial planets and gas planets with an educational spectrograph. It was installed in a 12-inch re ecting telescope at the Korea Science Academy of KAIST in Busan. Both spectra show clear absorption lines of re ected sunlight. They shows differences oin line presence, but are not very significant. This work means that the spectrograph successfully observed the re ected spectra of planets and can detect dierences in spectra in terms of the absence and presence of absorption lines of planets.
