In Fig. what should be the value of d so that image is formed on the object itself .

Text Solution

Verified by Experts

For convex lens `:v=(-15xx10)/(-15+10)=30cm`
The refracted rays from lens should fall normally on the mirror for the image to coincide with the object.
`d+20=v=30`
`rArr d=10cm`
