Question

There is a point object and a plane mirrors. If the mirror is moved by 3.5cm away from

the object. Find the distance by which the image will move.​

Answer 1

Answer:

image will move by the distance of 3.5cm.

Explanation:

the distance of object and the image is same for plane mirror.

when you move the mirror away from the object, the object distance will increase.so, the image distance will also increase.

Answer 2

Answer:

According to the question,

Given

Δx

o

=0

Δx

m

=10

We know that,

X

im

=−X

om

or, X

i

−X

m

=X

m

−X

o

or Δx

i

−Δx

m

=Δx

m

−Δx

o

So here we have,

Δx

o

=0

Δx

m

=10

since Δx=2Δx

m

−Δx

o

=20cm

Hence, the distance which the image is moved is =20cm
