if someone want to explain to me what is an upright image ? , and what are the other adjectives to define an image in geometric optics and their meaning , Thanks .
Also ‘laterally inverted’ is a good description in many circumstances. All three terms are probably easier to recognise than to describe.DaveC426913 said:A quick Google will straighten that out for you.
Hint: the opposite of 'upright' is 'inverted'.
