Energy transfer by radiation

Thermal radiation is energy transport by electromagnetic oscillations. This unit investigates Kirchhoff's laws and the effects of wavelength using colour filters, a thermal radiator, and a light source.

• investigation of thermal radiation and illuminance
• absorption and reflection plates with thermocouples for Kirchhoff's laws
• adjustable radiant power
• includes red, green, and infrared colour filters
• thermopile for radiant power and luxmeter for illuminance measurement
• software for data acquisition via USB under Windows 11
