(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Harmonic wave is described by:h(x,t)=cos(2∏(2x-t/2)). The equation is expressed as the height of the wave

At time t_{0}a peak of the wave is at position X_{0}.What is the magnitude of the distance to the nearest peak at this time? How much time passes before another peak is observed at that postion?

2. Relevant equations

Period=2∏/B; Acos(B(X-D))

3. The attempt at a solution

I figured that the first part of the question is asking the wavelength and the second part of the question is finding the period. I simplified the equaiton to cos(4∏(X-t/4)). I don't really know how to distinguish the wavelength from the period from the given equation. They both make sense to equal 1/2.

Thanks for your help in advance!
