Questions about Non-Optical telescopes:
1) A radio telescope with a reflecting dish of diameter d
receives signals from a radio source. Show that the power of
the signal received by the telescope is proportional to d2.

2) Modern astronomy relies on the analysis of radiation from
many different parts of the electromagnetic spectrum. Compare
the main features of telescopes used to detect radio waves
with those of optical reflecting telescopes. Explain the
differences in their resolving and colleting powers.
