What the syllabus asks
- understand the term luminosity as the total power of radiation emitted by a star
- recall and use the inverse square law for radiant flux intensity F in terms of the luminosity L of the source F = L /(4πd2 )
- understand that an object of known luminosity is called a standard candle
- understand the use of standard candles to determine distances to galaxies
How hard the questions are
