A person standing in front of a plane mirror approaches the mirror
A person standing in front of a plane mirror approaches the mirror by 40 cm. The new distance between the person and his image in the plane mirror is
- 60 cm
- 1.4 m
- 1.2 m
- 2.0 m
Answer
According to the question,
New distance between the person and the mirror = 100-40 = 60 cm
New distance between the person and the image in the plane mirror = 2* New distance between the person and the mirror = 2*60 = 120 cm = 1.2 m
The correct option is C.
