high-frequency sound waves exhibit less diffraction than low-frequency sound waves do. However, even high frequency sound waves exhibit much more diffraction under normal circumstances than do light waves that pass through the same opening. The highest frequency that a healthy ear can typically hear is 2.0 × 104 Hz. Assume that a sound wave with this frequency travels at 344 m/s and passes through a doorway that has a width of 0.95 m. (a) Determine the angle that locates the first minimum to either side of the central maximum in the diffraction pattern for the sound. (b) Suppose that yellow light (wavelength = 567 nm, in vacuum) passes through a doorway and that the first dark fringe in its diffraction pattern is located at the angle determined in part (a). How wide would this hypothetical doorway have to be?
A cold distance planet has an atmosphere of hydrogen (speed of sound = 1320 m/s) over a liquid ocean of carbon dioxide (speed of sound = 259 m/s).
A sudden shift in the rocky crust beneath the ocean creates a sound wave that heads toward the surface at an angle of 7 degrees.
At the surface, the wave is refracted with a refraction angle of . . .
Group of answer choices
49 degrees.
38 degrees.
The wave undergoes total internal reflection.
80 degrees.
A radio station broadcasts at a frequency of 85.9 MHz on your dial using radio waves that travel at 3.00 × 10^8 m/s. Since most of the station's audience is due south of the transmitter, the managers don't want to waste any energy broadcasting to the east and west. They decide to build two towers, transmitting in phase at exactly the same frequency, aligned on an east-west axis. For engineering reasons, the two towers must be AT LEAST 10.0 m apart. What is the shortest distance between the towers that will eliminate all broadcast power to the east and west?

- Two towers of a radio station are 0.6 km apart along an east-west line. The towers act as point sources radiating at a frequency of 1.0 x 106 Hz. Radio waves travel at a speed of 3.0 x 108 m/s.

Inside the box at one end is a small radio transmitter that emits radiation with a wavelength of 0.120 m. A receiver is placed at the other end, 7.20 m away. Assume both the transmitter and the receiver are on the floor of the box. The walls and floor of the box interior are treated to minimize reflection of radio waves. The ceiling of the box interior, however, is metal, so the radio waves can reflect off of it almost perfectly. The radio waves can take two paths from the transmitter to the receiver: a straight-line path, and a path that reflects off the ceiling of the box interior. Note that there is a phase shift when the waves reflect off the ceiling.
