Question

An object is placed at 80 cm in front of a plane mirror. If the mirror is now moved 30 cm away from the object, how does the image shift from its previous position? ​

Answer 1

$\huge\underline\mathfrak\purple{Bts}$

In this case, the mirror is moved 25 cm away from its initial position. Therefore, if the mirror is moved with distance x, then image in the mirror will move by distance 2x.

That is, 2x=50 cm.

So, the image will shift by 50 cm away from its previous position.

Answer 2

Answer:

In this case, the mirror is moved 25 cm away from its initial position. Therefore, if the mirror is moved with distance x, then image in the mirror will move by distance 2x.

That is, 2x=50 cm.

So, the image will shift by 50 cm away from its previous position.
