The three longest wavelengths that are reflected by the pilings.

Question

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?

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?
