A Level Physics worksheet containing questions about the lesson: Stellar Radiation & Luminosity
Model Answers Included
This worksheet covers 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 is tailored for the OCR A specification, however, the versatile nature of this resource makes it suitable for other exam boards too.
