Question

an object 1cm high produces a real image 1.5 cm high when placed at a distance of 15 cm from a concave mirror. calculate the position and magnification

Answer 1

as it is a concave lens the image will always be formed on the same side of the lens where the object is placed

U can also calculate the position by the formula... Length of image /length of object = distance of the image /distance of the object
1.5/1=15/x =>x=10 cm... Which means that the image is on the same side where the object is placed....

Magnification =length of the image
________________
Length of the object
=>1.5/1 = 1.5

Hope it helps!

Answer 2

magnification -3/2
position of image = -{1.5 ×3/2 }
