Mighty mule problem
In a dispersive medium, the phase speed itself depends upon the frequency of the wave, making the relationship between wavelength and frequency nonlinear. In the case of electromagnetic radiation—such as light—in free space, the phase speed is the speed of light, about 3×10 8 m/s. the relation between the wavelength of the fundamental tone formed and the frequency of the source, the speed of sound in air at room temperature can be estimated. www.praxilabs.com PHYSICS Waves Speed of Sound Using Open Columns Theoretical Background/Context When a sound source (wave generator) is held at one
Given: frequency. Asked for: wavelength. Strategy: Substitute the value for the speed of light in meters per second into Equation 6.2 to calculate the wavelength in meters. Solution: From Equation 6.2, we know that the product of the wavelength and the frequency is the speed of the wave, which for electromagnetic radiation is 2.998 × 10 8 m/s:
Jul 26, 2009 · You said, in your first post: "wavelength = V/f , with V being constant, 1493 m/s". If you were trying to find the wavelength, given the frequency, you could use that formula. But you said you were trying to find the speed of sound in water which, as you said, is 1493 m/s! Jul 26, 2009. #15. Other answers give the basic theory of EM waves. Frequency is inversely proportional to wavelength, since speed is fixed. Amplitude is independent of both. But it's not so simple in a real-world physical medium! Water waves (a.k.a. gravity waves) ...
