4.6.2.2 Required practical 10 — Infrared radiation

What you do (method)

• Compare emission/absorption using different surface finishes (matt black vs shiny).
• Measure temperature change with a thermometer/temperature probe.
• Keep distance/time/starting temperature controlled.

Common mistakes

• Not controlling variables between trials.
• Confusing emitters and absorbers (good emitters are good absorbers).
