Solutions To The Spherical Wave Equation

[RESolo]

If the solution to the electric part of the spherical wave equations is:

E(r, t) = ( A/r)exp{i(k.r-ωt)

What happens when t=0 and the waves originates at the origin, i.e. r=0 ... which I assume can't be right as you of course cannot divide by zero.

Thanks!

Hint: what happens if you take the limit towards zero of r and take t=0?

 

[RESolo]

Te exponential approaches 1 and you have A/r, the same problem? Can you just tell me I'm running out of time here!

I can't PF rules won't let me.
