a) You have learnt that plane and convex mirrors produce virtual images of objects. Can they produce real images under some circumstances ? Explain.

Use the mirror equation to deduce that : d) an object placed between the pole and focus of a concave mirror produces a virtual and enlarged image. [Note : The exercise helps you deduce algebraically properties of images that one obtains from explicit ray diagrams.]

    when object is kept at a distance less then its focal length
    C
    when object is placed between the focus and centre of curvature
    D
    when object is kept at a distance greater then its radius of curvature

    What is a virtual image ?

    If focal length of the concave mirror is 20 cm, we get virtual image if the object placed at a distance……..than 20 cm

    The image formed due to a concave mirror is highly enlarged when the object is placed

    Use the mirror equation to deduce that : b) a convex mirror always produces a virtual image independent of the location of the object. [Note : The exercise helps you deduce algebraically properties of images that one obtains from explicit ray diagrams.]

    Do we get an image with a concave mirror at the focus every time ? Let us find out.

    The image formed by a concave mirror is observed to be virtual, erect and large than the object. Where should be the position of the object ?
