Homework Equations
(kx-wt)
lambda=2pi/k
The Attempt at a Solution
Basiclly I think I can solve the rest if i understand this problem. The wavelength= 2pi ?
but when i solve for k... k=2pi/lambda, k is one. the answer should give me that k is 2, and the only way i can get that is if the wavelength is pi. Can anyone please help me to understand this?
