how we get "e^(ikr)"...?
Plz ans me... Thanks

There's no ##r## in the discussion above, so it's not clear what you're asking about when you write ##e^{(ikr)}##, nor does ##e^{e(x-ct)}## make sense in the context of this discussion.Though it's e^(e(x-ct))
Instead of treating space as a vector and time as a scalar, they are using the relativistic approach of a four-vector which combines the two into a single vector with 4 terms. Notice that the inner product is positive for the time term and negative for the space term. Some use the opposite sign convention for the inner product so one should be careful.arslan786786 said:sir please look at the electric field expression...
They are writing E°e^(ikr). The author puts r value...
I have searched a lot for it and I found its solution...
But i found that they calculate it with a very different method... They calculate 2pifn. x= wt-2pifn.x...
You can see in the image below...

No idea what you are even asking.arslan786786 said:View attachment 280810here is the screen shot sir...!
