An object is placed 1.5 m from a plane mirror. How far is the image from the object?
-
3.0 m
- 1.3 m
- 1.0 m
- 0.3 m
The correct answer is: A
Explanation
When an object is placed in front of a plane mirror, the image formed is at the same distance from the mirror as the object but on the opposite side.
Thus, the total distance between the object and the image is 1.5 m + 1.5 m = 3.0m
