A convex lens of focal length `50cm` is placed `20cm` in front of a plane mirror. Light from very far away source falls on the lens. The distance of final image from the mirror is

A diverging lens of focal length 10cm is placed 10cm in front of a plane mirror as shown in Fig. Light from a very far away source falls on the lens. What is the distance of final image?

A diverging lens of focal length 10cm is placed 10cm away in front of a plane mirror as shwon in figure. Light from a very far away source falls on the lens. An observer is situated some where in between lens and mirror, and observer is looking towards mirror. The observer will see the image behind teh mirror at a distance.

An optical system consists of a thin convex lens of focal length 30 cm and a plane mirror placed 15 cm behind the lens. An object is placed 15 cm in front of the lens. The distance of the final image from the object is

A thin convex lens of focal length 30 cm is placed in front of a plane mirror. An object is placed at a distance x from the lens (not in between lens and mirror ) so that its final image coincides with itself. Then, the value of x is

A convex lens of focal length 15 cm is placed on a plane mirror. An object is placed at 30 cm from the lens. The image is

A biconvex lens of focal length 15cm is in front of a plane mirror. The distance between the lens and the mirror is 10cm. A small object is kept at distance of 30cm from the lens. The final image is

A convex lens of focal length 20cm is placed 10cm in front of a convex mirror or radius of curvature 15cm. Where should a point object be placed in front of the lens so that it images on to itself?

An object is placed at a distance f in the front of a convex mirror. If focal length of the mirror is f, then distance of image from pole of the mirror is

A convex lens of focal length 20 cm is placed in front of a convex mirror of focal length 15 cm at a distance of 5 cm. An object of length 2 cm is placed perpendicular to the common axis at a distance of 20 cm from the lens

A convex lens of focal length 10cm is placed 30 cm in front of a second convex lens also of th esame focal length. A plane mirror is placed after the two lenses. Where should a point object be placed in front of the first lens so that it imagees on to itself?
