Two sources of electromagnetic waves (light waves) are emitting coherent waves at a frequency of 546 THz. These two sources are located a distance d apart and aimed at point A, as shown below. If the top source is located a distance 3.8 meters away from point A, find the minimum distance d that will give destructive interreference. Enter your answer in millimeters. 4₁ Laser Laser d A

The 305-m-diameter Arecibo radio telescope pictured in Figure 4.20 detects radio waves with a 4.00-cm average wavelength. (a) What is the angle between two just-resolvable point sources for this telescope? (b) How close together could these point sources be at the 2 million light-year distance of the Andromeda Galaxy? Figure 4.20 A 305-m-diameter paraboloid at Arecibo in Puerto Rico is lined with reflective material, making it into a radio telescope. It is the largest curved focusing dish in the world. Although D for Arecibo is much larger than for the Hubble Telescope, it detects radiation of a much longer wavelength and its diffraction limit is significantly poorer than Hubble’s. The Arecibo telescope is still very useful, because important information is carried by radio waves that is not carried by visible light. (credit: Jeff Hitchcock)

The GPS network consists of 24 satellites, each of which makes two orbits around the earth per day. Each satellite transmits a 50.0- W (or even less) sinusoidal electromagnetic signal at two frequencies, one of which is 1575.42 MHz. Assume that a satellite transmits half of its power at each frequency and that the waves travel uniformly in a downward hemisphere.
