This resource is a complete lesson that covers Stellar Radiation & Luminosity for the OCR A Level Physics A course. However, it is useful for other exam boards too.
This lesson teaches the following content:
-use of Wien’s displacement law λmax ∝ 1/T to estimate the peak surface temperature (of a star)
-luminosity L of a star; Stefan’s law L = 4πr²σT⁴ where σ is the Stefan constant
-use of Wien’s displacement law and Stefan’s law to estimate the radius of a star.
-Hertzsprung–Russell (HR) diagram as luminosity-temperature plot; main sequence; red giants; super red giants; white dwarfs.
This lesson includes:
-A full presentation including 2 example questions with worked solutions.
-A worksheet with model answers, perfect to set as homework.
-Clear visual aids and diagrams to simplify complex concepts.
-Editable PowerPoint and Word document for easy customisation.
