Question

An object is at a distance 25cm in front of a plane mirror.The mirror is shifted 5 cm away from the object find The distance between the two positions of the image

Answer 1

as we know that the real distance between the mirror and object = distance between mirror and image so if distance between mirror and object is 30cm(25+5) therefore the distance between image and mirror is also 30cm
therefore the distance between 2 positions of the image is 60cm(30+30)

Answer 2

Answer:

hope this helps

first distance =distance between object and image

25+25=50cm

new distance=distance between object and image

30+30=60cm

i. distance between two positions=new distance-first distance=60-50=10cm
