How to specifically trigger a "500 - internal server error" error?

Question

Apache HTTP Server

On the server, there are various files at the root - they are open for viewing and downloading, something like a file washer.
Created a folder at the root of the server /var/www/1/, and in it an empty file called "test".
An empty .htaccess is also placed there. The
question is how can I cause an error 500 - internal server error in the client when I try to enter:
site.ru/1 and site.ru/1/test
Apache settings:

<Directory /var/www/>
  #Options Indexes FollowSymLinks
    Options Indexes
  AllowOverride None
  Require all granted
</Directory>
....
<Directory /var/www/1/>
  AllowOverride All
  Order allow,deny
  Allow from all
</Directory>

Answer 1

<Directory /var/www/>
    # ...
    Redirect 500 /1
</Directory>
