Question

4. An object is kept at 60 cm in front of a plane mirror
If the mirror is now moved 25 cm away from the
object, how does the image shift from its previous
position ?
please don't see in Google or some other app​

Answer 1

Answer:The image will shift (170-120)= 50cm away from the previous position

Explanation:

Suppose a plane mirror is kept at 60cm in front of an object. Now the position of the image made by the mirror is (60x2)= 120cm (inside the mirror) from the object. As shown is the figure, If we move the mirror 25cm from the object then it wil make the distance of mirror-object 60+25=85cm

So the new image of the object will be created at (85x2)=170cm away from the object.

Now we can say that the image will shift (170-120)= 50cm away from the previous position

Answer 2

Answer:

the image seems to shift 85 cm from the mirror and 145 cm from the object

Explanation:

distance of object from the mirror is =60cm

distance of object from the image is =60+60=120cm

when the mirror moved 25 cm more

Then-object distance from mirror is 60+25=85

hence object is now 85 cm away from mirror

and 120+25=145cm away from the image.

hope this is the thing you want
