Which one can be projected?
[edit]Near the top, the article states that "because the rays never really converge, one can project only a virtual image, but not a real image. Note that it cannot be obtained on a screen.
In contrast, a real image is an image in which the outgoing rays from a point on the object pass through a single point. It is easiest to observe real images when projected on an opaque screen".
Am I reading it wrong, or should the sentence in the first paragraph say "one can project only a real image, but not a virtual image"? 80.103.77.221 (talk) 21:23, 29 March 2014 (UTC)
You're right. That part of this entry needs to be fixed. I'll do it. — Preceding unsigned comment added by 69.203.112.118 (talk) 23:11, 6 April 2014 (UTC)
Pretty sure that bottom image is a convex and not concave mirror... — Preceding unsigned comment added by 50.196.135.125 (talk) 18:47, 1 May 2014 (UTC)
Why is virtual object redirected here?
[edit]In optics, a virtual image and a virtual object are different. A virtual image is an image composed of diverging light. A virtual object is an object that is composed of converging light. A real object creates diverging light. A real image is created by converging light. Dradamh (talk) 07:59, 27 September 2016 (UTC)
The infinity case
[edit]If the object is at the focal point, the 'image' is at infinity: shouldn't that case be covered under the definition of 'virtual image'? Or should there be a third image type - real | virtual | infinity ? --195.137.93.171 (talk) 19:56, 17 April 2017 (UTC)
