Question

Q.9:  An object placed 4 m from a plane mirror it is shifted by 0.5 m away from the mirror. What is the distance between the object and its image?

Answer 1

Answer: 4.5 m

Explanation: The object and mirror are already placed 4.0m apart. In addition to that the object displaced away by 0.5m. Hence 4+0.5= 4.5 m

Answer 2

Answer :

Distance between the object and the image is 18 m.

Step-by-step explanation :

As the object is shifted by 0.5 m from a plane mirror,

Hence, the total distance between mirror and object will be,

→ 4 + 0.5

→ 4.5 m

Now,

Distance between the object and mirror is,

→ 4 × 4.5

→ 18 m

Hence, Distance between the object and the image is 18 m.
