In air, the wavelength is 3m, and its speed is 340m / s. What is the speed of this wave in water if its wavelength is 12 m?
Initial data: λair. (wavelength in air) = 3 m; υair. (wave propagation speed in air) = 340 m / s; λwater. (wavelength in water) = 12 m.
The wave speed in the aquatic environment can be determined from the equality: T = λair. / υair. = λwater. / υvod., whence υvod. = λwater. * υair. / λair ..
Calculation: υvod. = 12 * 340/3 = 1360 m / s.
Answer: The wave speed in the water is 1360 m / s.
