TY - JOUR ID - 1308736 AU - Bochníček, Zdeněk PY - 2015 TI - Linear halogen bulb as a powerful light source for physics experiments JF - European Journal of Physics VL - 36 IS - 6 SP - "nestránkováno" EP - "nestránkováno" PB - IOP Publishing SN - 01430807 KW - optics KW - demonstration experiments KW - spectrum UR - http://iopscience.iop.org/0143-0807/36/6/065001/ N2 - The paper describes the usage of a conventional lamp equipped with a linear halogen bulb for physics experiments. The irradiance gain and limitation of spectral resolution are treated in detail theoretically and verified experimentally. The analysis shows that, in comparison with a standard bulb and slit arrangement, the linear bulb can increase irradiance of the spectrum image in an order of magnitude without a significant loss of a spectral resolution in comparable experimental arrangements. Some concrete examples of experiments with a white light spectrum and diffraction are presented. ER -
