RELATED QUESTIONS

If the image formed by a mirror for all positions of the object placed in front of it is always erect and diminished, what type of mirror is it? Draw a ray diagram to justify your answer. Where and why do we generally use this type of mirror?


It is desired to obtain an erect image of an object, using concave mirror of focal length of 12 cm.

Will the image be smaller or larger than the object? Draw ray diagram to show the formation of image in this case.


To construct ray diagrams, two rays of light are generally so chosen that it is easy to determine their directions after reflection from a mirror. Choose two such rays and state the path/direction of these rays after reflection from a concave mirror. Use these two rays to find the position and nature of the image of an object placed at a distance of 8 cm from a concave mirror of focal length 12 cm.


According to New Cartesian Sign Convention:

(a) focal length of concave mirror is positive and that of convex mirror is negative
(b) focal length of both concave and convex mirrors is positive
(c) focal length of both concave and convex mirrors is negative
(d) focal length of concave mirror is negative and that of convex mirror is positive


An object is placed at a distance of 10 cm from a concave mirror of focal length 20 cm.

  1. Draw a ray diagram for the formation of image.
  2. Calculate the image distance.
  3. State two characteristics of the image formed.

Draw the ray diagram and also state the position, the relative size and the nature of image formed by a concave mirror when the object is placed at the centre of curvature of the mirror.


According to cartesion sign convention, which mirror and which lens has negative focal length?


Examine the above figure and state which of the following option is correct? [one small box in the figure is equal to 1 cm]


Rays from Sun converge at a point 15 cm in front of a concave mirror. Where should an object be placed so that size of its image is equal to the size of the object?


A student wants to obtain an erect image of an object using a concave mirror of 10 cm focal length. What will be the distance of the object from mirror?
