Question

ii)
At which position will you keep an
object in front of a convex lens so as to
get a real image of the same size as the
object? Draw a figure.​

Answer 1

Answer:

1.    In case of mirrors,when the object is at “C”(centre of curvature)a real, inverted image of the same size is formed at “C”

1.    In case of lenses, when the object is at “2F1”(twice of focal length), a real,inverted image of the same size is formed at “2F2” HOPE THIS HELPS!…GOOD LUCK……..Its better if you draw the ray diagrams and see yourself.
