Your best bet is to read the mod_rewrite documentation which explains how rewrite works. From that page:
Summary The mod_rewrite module uses a rule-based rewriting engine,
based on a PCRE regular-expression parser, to rewrite requested URLs
on the fly. By default, mod_rewrite maps a URL to a filesystem path.
However, it can also be used to redirect one URL to another URL, or to
invoke an internal proxy fetch.
mod_rewrite provides a flexible and powerful way to manipulate URLs
using an unlimited number of rules. Each rule can have an unlimited
number of attached rule conditions, to allow you to rewrite URL based
on server variables, environment variables, HTTP headers, or time
mod_rewrite operates on the full URL path, including the path-info
section. A rewrite rule can be invoked in httpd.conf or in .htaccess.
The path generated by a rewrite rule can include a query string, or
can lead to internal sub-processing, external request redirection, or
internal proxy throughput.
So the path is whatever you want it to be.
