An object is placed at a distance of 50cm in front of a mirror of focal length 25cm. Find the image distance. If the object is 10cm high what will be the nature and size of the mirror?

1 answer

Draw a picture
parallel ray from top bounces off and heads through center line at 25 cm from mirror
ray through focus from top comes out parallel below

rays intersect right below original
so:
same distance from mirror
same height but upside down.
