Aconcave mirror can form a real image, which is a copy of an object that forms where light rays reflect off the object where light rays disperse where light rays actually meet

I hope I can help! :)

A concave mirror is when the object is anywhere from infinity to focus the image so form will be real and inverted.

And when the object is between pole and focus of concave mirror then image so formed will be virtual and erect and the size of image is greater than size of object.

So, the answer would be "where light rays disperse."

Have a great day/evening/night! :)
Let me know if you have any additional questions!
