| Description | 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. |
