If object distance is 5 m for a plane mirror, then the image distance is:
If AB is an object, CD is an image formed. If AP is object distance CP is image distance from the mirror. Then choose the correct sign convention.
1. height of image = + ve 2. height of image = – ve
3. height of object = + ve 4. height of object = – ve
5. AP = + ve 6. AP = – ve
7. PC = + ve 8. PC = – ve.
