This unit looks at how telescopes and spectrographs are designed to improve our ability to observe the universe. You will examine how different technologies have been developed over the last four hundred years to enable us to look deep into space.
By the end of this unit you should be able to:
- understand the application of basic principles in geometrical optics;
- appreciate the phenomena relating to the wave nature of light.

Telescopes and spectrographs
We are used to seeing spectacular astronomical images in the press and on the internet. This unit gives an in-depth introduction to two of the most important instruments used to create these images and explore the science behind them – telescopes and spectographs.
This unit is drawn from the preparatory work for the practical residential school at the Observatori Astronomic de Mallorca. The unit image shows a student at work in one of the telescope domes at the Observatori.
This unit is used for training by the Faulkes Telescope Project, http://faulkes-telescope.com/.
