" How to spread light on the spectral lines "- spectral analysis of light

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

organizational culture-a Code of Ethics work and behavior


On 28.04.2011 was held classes in which we discussed, among others a moral and ethical responsibility for the performance of their duties.

Thanks to these occupations have learned how to use ethics to do good business. At the end of jointly reflected on the Code of Ethics for our company.

"Where a man can not, there will send a photon - the practical application of photons.

On 11 April there were more classes in mathematics and natural sciences.

aim of our activities was to gain knowledge on:
- photocells and the principle of its operation
- fotoogniwie
- fotorezystorze.

Our work in class was to work independently with a computer. Thanks to his knowledge of the photovoltaic cells, photocells and light dependent, and by other sources information have made multimedia presentations. After work, each presented their work.
