Question 168242: The speed of a wave varies jointly with the wavelength and the frequency of the wave. If the speed of a wave is 20 feet per second, its wavelength is 50 feet and its frequency is 0.4 waves per second. What is the speed of a wave whose wavelength is 1 foot and whose frequency is 8 waves per second? Answer by Mathtut(3670) (Show Source):
You can put this solution on YOUR website! formula would read speed of the wave= constant(wavelength)(frequency)
is the speed of the wave. w is the wave length
....................and f is the frequency
20=k(50)(.4)
20=20k
k=1
so
