1.An object is placed

If two mirrors are inclined at some angle theta . An object is placed between the mirrors and there are 5 images formed for an object, then theta is may be

{:("Column I","Column II"),((A)" An object is placed at a distance equal to focal length from pole before convex mirror",(p)" Magnification is "(infty)),((B)" An object is placed at focus before a concave mirror",(q)" Magnification is (0.5)"),((C) "An object is placed at the centre of curvature before a concave mirror" , (r) "Magnification is (1//3)") , ((D) " An object is placed at a distance equal to radius of curvature before a convex mirror" , (s) "Magnification is (-1)"):}

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

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

The focal length of objective and the eyepiece of a compound microscope are 1cm and 5cm. An object is placed at a distance of 1.1 cm from the objective and if the final image is formed at infinity the magnifying power and distance between the lenses are respectively

Two plane mirrors are plaved parallel to each other and 40 cm apart. An a object is placed 10 cm from one mirror .What is the distance from the object to the image for each of the five images that are closest to the object?

A convex and a concave mirror of radii 10 cm are placed facing each other and 15 cm apart. An object is placed exactly between them. If the reflection first takes place in concave and then in convex mirror the position of the final image will be

When the height at which an object is placed is more, the PE .......

An object is placed at the focus of an equiconvex lens. Match the following

When an object is placed between two parallel mirrors, then number of images formed are
