A wave is described by the function y(x,t)=(3.00cm)cos((3.00m)x+(400s) What is the wavelength of this wave? Select one 1.57 m 3.00 m 0.250 m 2.09 m 0.333 m

The correct answer is 3.00 m.The given wave function is . In this function, the term represents the wave number, which is related to the wavelength by the equation , where is the wave number. In this case, , so the wavelength . Therefore, the correct answer is 3.00 m.
