China Wholesale liquid heat vaporization Suppliers – LEAT-3 Measuring Instrument for Specific Heat of Vaporization of Liquid – Labor

Short Description:

The polarization state of the light can be manipulated by the angle of the rotating polarizer and the wave plate. The polarizer turns the natural light into polarized light, and the wave plate can change the polarization state of the light. In this experiment, the rotation of the motor drive polarizer and wave plate can be used to display the experimental results of complex polarized light to the students through the computer interface.
