An object is placed at a distance 20 cm from a convex lens of focal length 10 cm . Find the image distance and nature of the image .

Text Solution

Verified by Experts

u=- 20 cm
f=10 cm
`(1)/(f)=(1)/(v)-(1)/(u)`
`(1)/(v)=(1)/(f)+(1)/(u)`
`(1)/(v)=(1)/(10)+(1)/((-20))`
`(1)/(v)=(1)/(10)-(1)/(20)`
`v=(1)/(20)rArrv=20cm`
Nature of the image real enlarged and inverted image.
