## Homework Statement

Hi, Let's say that I measure the position of a system and I get that it is at X. So then if immediately after I measure the momentum, will I get:

1/sqrt(2*pi)* integral (exp(ikX))*(exp(-ikx))dx?

But this integral is undefined?

Then how do I find the momentum wave after measuring position? Thanks!

Or will my momentum just be exp(ikX)? for all range of K?

Thanks.
