Have you ever wondered why stars look different colours? What do these colours mean? How do we know what stars are made of? Explore these questions with our classify a star activity. Use Wien’s displacement law to work out the temperatures and classifications of some real stars!
By the end of this resource you will:
- Have used Wien’s displacement law to calculate the temperature of a star
- Used Wien’s displacement law on real stellar data
- Analysed a stellar spectrum to find absorption lines
To complete this resource you will need:
- The worksheet below
- A calculator
- A pen/pencil
