What is the y component of the magnetic field at point O at time 0.227*E-16 s?
Given: Frequency: 2.20*E16 Hz
Max value of B-field: 4.00*E-8T when t = 0 at point O
I think the following two equations could potentially be applied to the problem:
B = B_max*sin(kx-wt)
The Attempt at a Solution
I know w = 2*Pi*f (where f is the given frequency)
t = the given time
I guess I'm not sure how to find k & x, or if this is even the correct manner in which to solve the problem.
