Question

An object is 4 m from a plane mirror. If mirror moves further away by 6 m, by how much does the image move from initial position.

Answer 1

Answer:

I am assuming that the distance measured is the perpendicular distance between mirror and object. Initially, the distance between the object and image would be 8 m. (Because the image is as far from the plane mirror as the object is. So 4 × 2 = 8)

When the object is moved one metre closer, the distance between the object and plane mirror is 3 m.

Therefore, the new distance between the object and image is 6m

Answer 2

Answer:

6m

Explanation:

correct answer is 6m
