The light rays from an object have been reflected towards an observer from a standard flat mirror, the image observed by the observer are :-
A. Real
B. Erect
C. Smaller in size then object
D. Laterally inverted

Choose the most appropriate answer from the options given below :

(A)B and D only✓ Correct
(B)B and C only
(C)A and D only
(D)A, C and D only

Answer: (A)

Solution

A plane mirror sends back diverging rays that only appear to meet behind it, so the image is virtual rather than real. It stands the same way up as the object, keeps the same size, and has its left and right interchanged. Of the properties listed, only erect and laterally inverted describe such an image.
