Question:
An object is placed 50cm in front of a mirror.Now both the object and the mirror are moved 10 cm towards each other. What will be the distance between the object and the image?
Answer:
The distance between the object and the image is 60 cm.
Given:
The distance between the object and the mirror is 50 cm.
Both the object and the mirror are moved towards each other by 10 cm.
To find:
The distance between the object and the image.
Explanation:
The distance between the object and the image is 50 cm.
Both the object and the mirror are moved to each other by 10 cm.
Hence,
The distance between the object and the mirror becomes_
(50-10-10) cm
= (50-20) cm
= 30 cm
We know that,
The distance between the object and the mirror = The distance between the image and the mirror.
∴ The image will form at a distance of 30 cm behind the mirror.
∴ The distance between the object and the image is = (The distance between the object and the mirror + The distance between the image and the mirror)
= (30+30) cm
= 60 cm.
∴ The distance between the object and image is 60 cm.
