The Measurement of Wavelength Spectrum on Grating Observation

Item no.: F23 Introduction In general, light spectrum could be classified into discrete spectrum and continuous spectrum. However, both absorption and emission are the main typical pattern for discrete spectrum. Unlike the discrete way mentioned above, typical continuous spectrum, in this experiment, will be investigated. Here a slice with 500line / mm grate will be
