Homework Equations
In question.
The Attempt at a Solution
To be clear it's part (vi) that's unclear to me.
In order to ignore the cosine term it has to reduce to 1. This can happen, only if k(x1+x2)/2 = ωt
Is this a correct assumption ?
Also, it is known that k = 2∏/λ and ω=2∏/T
However, I'm trying to think in what way these two components could be equal but I can't get it.
Could someone give me some help, please ?
