The problem calls for finding the relationship between the constants A and B in the following equation of an instantaneous electric field:
The details of the medium in which the field exists are that it is homogenous, isotropic, linear, and is source-free.
The Attempt at a Solution
I really have no idea how to go about solving this problem. Initially I was thinking I was just playing around with the vector equation by seeing what it looks like when I plug in different values of x and y and when t=0 or 1. Here is what that looked like:
Can someone please help point me in the right direction?
