A paralel beam of light incident on a concave lens of focal length 10 cm emerges as a parallel beam from a convex lens placed coaxially, the distance between the lenses being 10 cm. The focal length of the convex lens in cm is

An index pin of height 3 cm is kept at a distance of 15 cm from a convex lens of focal length 10 cm. The image is obtained on a screen placed on the other side of the lens. What is the height and nature of the image ?

A converging beam of light is incident on a concave lens of focal length 20 cm. In the absence of the lens, the beam converges at a point 10 m behind the lens. Find where the beam will converge/diverge after refraction.

An object placed at 20 cm from a lens, forms an image on a screen placed 60 cm on the other side of the lens. What is the focal length and type of the lens ?

An object is placed at f//2 away from first focus of a convex lens where f is the focal length of the lens. Its image is formed at a distance 3f//2 in a slab of refractive index 3//2 , from the face of the slab facing the lens. Find the distance of this face of the slab from the second focus of the lens.
