1. The figure shows a loudspeaker A and point C, where a listener is positioned. IACI = 2.50 m and the angle 0 = 50 °. A second loudspeaker B is located somewhere to the left of A. The speakers vibrate out of phase and are playing a 61.0 Hz tone. The speed of sound is 343 m/s. What is the third closest distance to speaker A that speaker B can be located, so that the listener hears no sound?

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)
Two identical audio speakers connected to the same amplifier produce in-phase sound waves with a single frequency that can be varied between 340 and 575 HzHz . The speed of sound is 340 m/sm/s . You find that where you are standing, you hear minimum-intensity sound If one of the speakers is moved 39.8 cmcm toward you, the sound you hear has maximum intensity. What is the frequency of the sound? Express your answer in hertz. How much closer to you from the position in part B must the speaker be moved to the next position where you hear maximum intensity? Express your answer in meters.
