(Concave mirrors)Since the reflected converging rays meet, why wont a real image be formed?

Question

Answer 1

Note that the parallel rays that are falling in the concave mirror are coming from A POINT of an object or source of light.

If and only if the object is very far away (infinite distance) the rays from the object will be parallel even though the object is huge. If not the rays will be divergent.

For example the sun is very big considered to our earth. The rays from any point of the sun will be reaching at any place on our earth only in parallel beam of light.

In the given case, the rays are coming from a point far away from the mirror and even though the object or source is very big, the rays after reflection actually produce a point image.

If you consider all parallel rays (rays that are not parallel to the principle axis), then we can see that there is tiny REAL image of the object.

Answer 2

i think u r a lil bit confused .in all cases except when the object is placed on focus the nature of image formed in concave mirror is real and in optical sciences any image which is formed is inverted it is known to be real.the image of ours which we see on plane mirror is a virtual image and is not real.

Answer 3

I think you would see a real image if there were something there to reflect it. Can light be seen, apart from objects lit?

Answer 4

Here , i would say you have a real image

Answer 5

u`ll have a real image. unless u have a virtual object.
