do you see the image is that big or small not the distance between you your face and spoon in centimetre
Answers
Answer:
The assumption that the image is inverted and virtual is not correct. If the image is inverted it is real. Only virtual images are erect.
Why is the image inverted? This is because the concavity of the spoon is generally such that the distance from the spoon of the object that we are viewing is generally more than the focal length of the spoon. When the object is at a distance greater than the focal length the image is inverted. Such images are real images.
In case the object that we are viewing is at a distance lesser than the focal length (which can happen with comparatively “much flatter” spoons) the image would be erect and virtual.
