How are the images formed in convex mirror when object is moved from infinity to
the mirror?
Answers
When object is at infinity - Image formed at focus. Real ,inverted and extremely small.
When object is near to centre of curvature - Image formed between focus and centre of curvature. Real, inverted and small in size than object size.
When object is on centre of curvature - Image formed at centre of curvature. Real, inverted and same size as object size.
When object is between centre of curvature and focus - Image formed beyond centre of curvature. Real inverted and larger in size.
When object is on focus - Image formed at infinity. Real, inverted and extremely large.
When object is between focus and optical centre - Image formed is virtual and can be seen in the lens only. Erect and magnified.
Points to remember-
As object moves towards focus, image moves away from focus.
As object moves towards focus, image moves away from focus.As object moves towards focus, image grows in size but remains inverted.
As object moves towards focus, image moves away from focus.As object moves towards focus, image grows in size but remains inverted.As object moves between focus and optical centre, image decreases in size virtually as distance from the lens decreases.
Answer:
When the object moves closer from infinity to pole, the Image also gets closer to the Pole.
Explanation:
This can be explained by taking the two conditions of image formation in a convex mirror:
1) When the object is at infinity, the position of the image is behind the mirror at focus F and is highly diminished and is virtual and erect.
2) When the object is between the pole of the mirror and infinity,the image is formed behind the mirror between the pole and the focus and is diminished and is virtual and erect.
Thus, by observing these cases. we can conclude that the image formed is closer when we move the object from infinity to pole.
