Question

what will be the distance between image and mirror if the distance between image and object is 10m​

Answer 1

Answer:

Let O be the origin and position of mirrors be A:5 m and B:−5 m

Then, I  

1

​  

O=2AO=10m

Hence, position of I  

1

​  

=10m

This serves as object for second image.

Then, I

​  

B=I  

1

​  

B=15m

I  

2

​  

O=I  

2

​  

B+OB=20m

Hence, position of I  

2

​  

=−20m

I

​  

I  

2

​  

=10−(−20)=30m
