IB Physics SL B.2.3 Albedo
Practise finding albedo from reflected and absorbed intensities, then using it in radiation-balance calculations for surfaces and planets.
How this is tested
- calculate albedo from intensity data or a diagram, and use equilibrium to infer the radiated intensity
- apply absorbed intensity = (1 - albedo) × incident intensity, including the S/4 average when required
- compare materials or regions by reflected intensity to decide albedo ratios or which surface absorbs more energy
