When a object is placed at 25 cm from a concave lens, a virtual image is produced at a distance 10 cm. Calculate the magnification produced by the lens. Given u=-25cm v=-10cm m=?

Answer»

SOLUTION :`m=("HEIGHT of the image")/("Height of the object")=(v)/(u)`
`=(-10)/(-25)=0.4`
MAGNIFICATION `m=0.4`
