Radio waves of wavelength 174 m from a galaxy reach a radio telescope by two separate paths as shown in the figure below. One is a direct path to the receiver, which is situated on the edge of a tall cliff by the ocean, and the second is by reflection off the water. As the galaxy rises in the east over the water, the first minimum of destructive interference occurs when the galaxy is θ = 24.5° above the horizon....

If the angular magnification of an astronomical telescope is 28 and the diameter of the objective is 67 mm, what is the minimum diameter of the eyepiece required to collect all the light entering the objective from a distant point source located on the telescope axis?

An astronomical radio telescope consists of two antennas
separated by a distance of 206 m. Both antennas are tuned to the
frequency of 24 MHz. The signals from each antenna are fed into a
common amplifier, but one signal first passes through a phase
selector that delays its phase by a chosen amount so that the
telescope can "look" in different directions. When the phase delay
is zero, plane radio waves that are incident vertically on the
antennas produce signals...

The Very Large Array (VLA) is a set of 27 radio telescope dishes in Catron and Socorro counties, New Mexico (see figure below). The antennas can be moved apart on railroad tracks, and their combined signals give the resolving power of a synthetic aperture 36.0 km in diameter. (a) If the detectors are tuned to a frequency of 1.17 GHz, what is the angular resolution of the VLA? 8.689 µrad (b) Clouds of interstellar hydrogen radiate at the frequency used...

Constants Part A The resolution of a telescope is ultimately limited by the diameter of its objective lens or mirror. A typical amateur astronomer's telescope may have a 7.0 in. -diameter mirror What is the minimum angular separation (in arc seconds) of two stars that can be resolved with a 7.0 in. scope? (Take ? to be at the center of the visible spectrum, about 550 nm, and note that 1 arc sec 1/3600 ) Express your answer using two...
