A point object is placed on the principal axis of a convex lens (f = 15 cm) at a distance of 30 cm from it. A glass plate `(mu= 1.50)` of thickness 1 cm is placed on the other side of the lens perpendicular to the axis. Locate the image of the point object.

A point object is placed on the principle axis of a converging lens of focal length 5cm at a distance of 30cm form it. A glass plate (mu = 1.50) of thickness 3cm is placed on the other side of the lens, comes out parallel to the principle axis?

A point object O is placed on the principal axis of a convex lens of focal length f=20cm at a distance of 40 cm to the left of it. The diameter of the lens is 10. An eye is placed 60 cm to right of the lens and a distance h below the principal axis. The maximum value of h to see the image is
