A wave is described by the function y(x,t)=(3.00cm)cos[(3.00m^-1)x+(4.00s^-1)t] What is the wavelength of this wave? Select one: 1.57 m 3.00 m 0.250 m 2.09 m 0.333 m

Question

Answer 1

The correct answer is 0.333 m.The given wave function is in the form of

, where

is the amplitude,

is the wave number, and

is the angular frequency.The wave number

is given by

, where

is the wavelength of the wave.In the given function,

. To find the wavelength, we can rearrange the equation to solve for

:

Therefore, the wavelength of the wave is 0.333 m.
