You are operating a new radio telescope that has been installed on a tall cliff facing the ocean. You begin the testing of the telescope by facing the antenna toward the ocean, setting its receiving wavelength to 125 m, and sweeping its direction slowly from horizontal to straight up in the sky.Each sweep takes about an hour. When you review the data, you notice that the antenna received no signals when aimed at a certain angle above the horizontal. You continue to take data beginning at the same time each night and discover that the angle at which no signals are detected varies from night to night. Over a full month, the angle at which no signals are detected varies from 24.5° to 25.7°. You finally figure out that the loss of signal is due to destructive interference caused by the reflection of radio waves from the ocean surface, and the monthly variation is due to the changes caused by ocean tides. You inform the local oceanographic institute that you have a novel method of measuring…
You wish to study the radio emission from the sun at wavelength 1.70 cm. In order to see details on the sun’s surface no larger than the diameter of the earth, the limit of resolution of the telescope must be 9.00 x 10-5 rad (about 0.005°). Using the Rayleigh criterion, find (a) the minimum diameter your radio telescope must have and (b) the limit of resolution of this telescope at wavelength 21.1 cm.
A telescope has a circular aperture of diameter D = 4.4 m. A light with wavelength λ = 690 nm travels through the telescope.  Express the limiting angle of resolution, θmin, in terms of λ and D. You may assume that θmin is very small.  θmin =
