The distance between an objects kept 20cm away from a plane mirror and its image is...
(10 cm,20cm,40cm)
Answers
Answer:
The image distance = - The object distance
The image distance = - The object distanceAn object is placed 20 cm in front of a plane mirror then the image is formed at 20 cm behind the mirror.
The image distance = - The object distanceAn object is placed 20 cm in front of a plane mirror then the image is formed at 20 cm behind the mirror.If the mirror is moved 2 cm toward the object.
The image distance = - The object distanceAn object is placed 20 cm in front of a plane mirror then the image is formed at 20 cm behind the mirror.If the mirror is moved 2 cm toward the object.The distance between object and mirror = 20-2 = 18 cm
The image distance = - The object distanceAn object is placed 20 cm in front of a plane mirror then the image is formed at 20 cm behind the mirror.If the mirror is moved 2 cm toward the object.The distance between object and mirror = 20-2 = 18 cmThe distance between image and mirror = 20-2 = 18 cm

Answer:
20 cm
Explanation:
An object is placed 20 cm in front of a plane mirror, then the image will form 20 cm behind the mirror because the image formed by a plane mirror is at the same distance behind it as it is between the object and the mirror.
