In order to observe emissions from celestial bodies Very Long Baseline Arrays (VLBA) have been developed. Explain why VLBA use multiple telescopes separated by long distances in terms of the wave nature of light. Include in your answer specific physics terminology, associated relevant equations, and a labelled diagram.
Describe the SPECT and PET imaging techniques.

If the intensity of the Sun peaks in the optical range, at a frequency of about 3:4 x 10 Hz, what is the temperature of the Sun? Use the Wien displacement law (1.25). If all of the power is emitted only between 3 and 4 x 10 Hz, how many photons per cm² arrive at the earth when the Sun is directly overhead? What is the power received on earth per cm³? A value for the solar power is 135mW per cm². How does this compare to your calculation?
