Black bodies as an ideal model
Black bodies as an ideal model
Any object above absolute zero emits electromagnetic radiation because it has thermal energy. This temperature-based emission is called thermal radiation, and radiation laws use temperature in kelvin.
Step-by-step lessons covering Edexcel A Level Physics Black-body radiation for A Level Physics. Each lesson works through exam-style questions in Paper 1, Paper 2 and Paper 3 format. Physics is one of the most mathematically demanding A Levels -- at least 40% of the marks across the three papers require maths skills at Level 2 (GCSE) standard or above, so build calculation and graph-handling fluency alongside the conceptual content from the start.
