Question

an object S placed in front of the plane mirror of length L at a distance d of its bisector line an observer is at a perpendicular distance of 2d from that mirror if the observer is walking parrellel to the mirror up-to what maximum possible distance he can observe the image of that object . Please answer correctly with explanation I will mark brainlist​

Answer 1

Answer:

An object is placed in front of the plane mirror of length L at a distance 'd' of its bisector line. An observer is at a perpendicular distance of '2d' from that mirror. If the observer is walking parallel to the mirror, upto what maximum possible distance he can observe the image of that object.

Explanation:

Let the maximum distance travelled by the observer be y.

Let C be the point in the straight line to the bottom of the plane mirror.

Let A be the point where the object is placed.

Let B be the extreme point where the observer can see the object in the mirror.

Now, the other extreme point from where the image can be seen be E.

Then from the diagram you can observe that the maximum distance the observer can cover such that he can see the object in the mirror will be BE.

Therefore, we can write.
