Write the position and nature of the image formed in a concave mirror if the object is kept (a) at infinity (b) at F (c) between F and C (d) at (e) beyond C (f) between F and P.

Draw ray diagrams showing the image formation by a concave mirror when an object is placed (a) between pole and focus of the mirror , (b) between focus and centre of curvature of the mirror (c) at centre of curvature of the mirror , (d) a little beyond centre of curvature of the mirror (e) at infinity

How is the position of image related to the position of the object for concave mirror of focal length f?

Use the mirror equation to deduct that : (a) an object between f and 2f of a concave mirror produces a real image beyond 2 f . (b) a convex mirror always produces a virtual image independent of the location of the object. ( c) the virtual image produced by a convex mirror is always diminished in size and is located between the focus and the pole. (d) an object placed between the pole and focus of a concave mirror produces a virtual and enlarged image.

Find the nature of image when an object is placed at 2f from the pole of a convex mirror of focal length f

If a,b,c,d,e, f are A. M's between 2 and 12 , then find a + b + c +d + e +f.

Consider a coaxial system of two thin convex lenses of focal length f each separated by a distance d. Draw ray diagrams for image formation corresponding to an object at infinity placed on the principal axis in the following cases: (a) d lt f ,(b) d=f , (c ) f lt d lt 2f , (d) d=2f , and (e) d gt 2f . Indicate the nature of the combination (concave, convex or plane) in each case.

The distance between an object and its doubly magnified image by a concave mirror is: [Assume f = focal length]

In an astronomincal telescope, the distance between the objective and the eyepiece is 36cm and the final image is formed at infinity. The focal length f_(0) of the objective and the focall length f_(e) of th eeyepiece are

A spherical mirror produces an image of magnification -1, when an object is placed on the principal axis of the mirror at a distance of 40 cm form its pole. (a) Identify the nature of image. (b) Identify the nature of spherical mirror. (c) Find the distance between the object and its image. (d) How will the nature of the image change, if the object is shifted 10 cm towards the mirror ? Draw a ray diagram to justify your answer. [Hint. (a) Image is real, inverted/same size as the object, (b) Concave mirror, (c) Zero, (d) Image will be formed beyond C, It will be larger in size.]

In the above question, if the rays were to converge between F and C of mirror, then find the nature of final image formed
