The speed of sound in dry air at 20 ∘C is 343 m/s and the lowest frequency sound wave that a gerbil ear can detect is approximately 56 Hz. What would be the frequency of electromagnetic radiation with the same wavelength? Express your answer to two significant figures and include the appropriate units.

The relations between wavelength, frequency, period, and speed of propagation apply to all wave phenomena, not just electromagnetic radiation. The C key on a piano has a fundamental frequency of about 256 Hz. What is the corresponding wavelength of the sound waves? (The speed of sound in air varies with temperature but is about 340 m/s at room temperature.)

A room contains air in which the speed of sound is 343 m/s. The walls of the room are made of concrete, in which the speed of sound is 1850 m/s. (a) Find the critical angle for total internal reflection of sound at the concrete-air boundary. ° (b) In which medium must the sound be traveling in order to undergo total internal reflection? air concrete (c) "A bare concrete wall is a highly efficient mirror for sound." Give evidence for...
The speed of sound through air at room temperature and standard pressure is about 343 m/s....
The speed of sound through air at room temperature and standard pressure is about 343 m/s. One cue the human hearing system uses to localize sound is the slight difference in the arrival times at the two ears of the sound emanating from a source. Ears are spaced about 20cm apart. Consider a person facing the positive x-direction and a source located 5 m away at an angle of 45° below the positive x-direction. What is the difference in arrival...
