05.05.11r Day. classes were held in which the observed spectrum of light from different sources. We also learned what it is photometry, spectroscope, spectrograph, spectral analysis, emission spectrum, absorption spectrum, the intensity of illumination.
Experiment 1
Subject: "The absorption of light by transparent substances"
Experimental:
between sources of light and the spectroscope to set clear the plate and observe the received spectrum. We compare the system of fringes obtained before and after inserting the plate between the light source and the spectroscope. Observations of conduct for all lamps with the experience of the first.
What do you think of which could result in the spectra observed differences?
Explanation: transparent substances absorb electromagnetic waves of this wavelength, which would emit the same if they were raised.
can repeat the experiment for a plate of different material or use color filter and observe the differences obtained.
interesting addition to classes may be present emission spectra of elements called "Spektruś. It can be viewed on: klub.chip.pl / mpytel / spektrus.hmtl
