Light sensor
Wireless light sensor: inverse square law, absorption, polarization and illuminance of workplaces in six experiments on optics.
The wireless sensor measures the illuminance and transmits the data to a digital laboratory system. It supports six experiments: checking the inverse square law for a point source, the dependence of illuminance on the angle of incidence of light, studying the transparency and absorption of light by media and light filters, measuring the illuminance of workplaces and comparing it with hygiene standards, demonstrating Malus’s law and the polarization of light using polarising filters, studying the flicker of alternating current lamps. The sensor is used in laboratory work on optics and in practical activities on lighting hygiene.
- Checking the inverse square law: dependence of illuminance on the distance to a point source
- Study of the dependence of illuminance on the angle of incidence of light on a surface
- Study of transparency and light absorption by media and filters
- Measuring illuminance of workplaces and comparison with hygiene standards
- Demonstrating Malus’s law and light polarisation using polarising filters
- Investigating fluctuations in illuminance from AC-powered lamps
