The lens shown is equiconvex having refractive Index. 1.5. In the situation shown the final image of object coincides with the object. The region between lens and mirror is now filled with a liquid of Rrefractive Index 2. Then find the separation between O & image formed by convex mirror.

An small object is kept at 18cm from combination of a convex lens and plane mirror to get the image on object itself. Now the space between lens and mirror is filled with liquid of refractive index muL . Now we need to keep the object at 27cm to get the image on object. Find muL .

A thin equiconvex lens of refractive index 3//2 is placed on a horizontal plane mirror as shown in figure. The space between the lens and the mirror is filled with a liquid of refractive index 4//3 . It is found that when a point object is placed 15 cm above the lens on its priincipal axis, the object coincides with its own image. Q. If another liquid is filled instead of water, the object and the image coincide at a distance 25 cm from the lens. Calculate the refractive index of the liquid.

A real image of an object is formed by a conex lens at the bottom of an empty beaker. The beaker is now filled with a liquid of refractive index 1.4 to a depth of 7 cm. In order to get the image again at the bottom the beaker shoud be moved

An equi-convex lens, having radius of curvature 33 cm is placed on a horizontal plane mirror and a pin held 20 cm above the lens coincides with its image. Now the space between the and the mirror is filled with a liquid in order to coicide with the image the pin has to be raised by 5 cm. The refractive index of the liquid is

An object is placed at a distance of 12 cm from a convex lens. A convex mirror of focal length 15 cm is placed on other side of lens at 8 cm as shown in the figure. Image of object coincides with the object. When the convex mirror is removed, a real and inverted image is formed at a position. The distance of the image from the object will be (cm) .
