Consider an ocean wave with a wavelength of 3 meters and a frequency of 1 hertz. Dividing speed by frequency gives you the wavelength. T is the period of the wave in seconds.
620 nm 1 m 109 nm 620107 m 620 nm 1 m 10 9 nm 620 10 7 m.
Subtract the initial speed. Calculating Wave Speed from Wavelength and Wave Frequency. In this problem it is mentioned that two sound waves wave X and wave Y are moving through a medium at the same speed. Sea reports give the significant wave height.
