Demonstration kit for Planck's constant
Areas of expertise and application The demonstration kit is designed to calculate Planck's constant based on measuring the turn-on voltage of a semiconductor laser and the wavelength of the light emitted by it. What will the child learn? Allows the user to perform experiments to determine the wavelength of a semiconductor laser, as well as determine Planck's constant. Working method Allows you to teach the main stages of conducting experimental research, and also allows you to conduct joint research with students. Composition: A platform on which a semiconductor laser and an electrical circuit are mounted, providing smooth regulation of the supply voltage Diffraction grating A ruler on which the diffraction spectrum is recorded The semiconductor laser is mounted in its own plastic housing, which is mounted on the platform in such a way as to ensure the possibility of rotating the beam in a plane perpendicular to the platform. Methodological support The set is accompanied by methodological instructions for performing experiments in Russian. Examples of experiments The kit allows you to perform the following experiments: Determining the wavelength of a semiconductor laser Determining Planck's constant Important: The product is included in the register of industrial products produced on the territory of the Russian Federation 2740\6\2022.
