Question

1. Draw a ray diagram to show the path of the reflected ray in each of the following cases.
* A ray of light incident on a convex mirror:
* strikes at its pole making an angle ө from the principal axis.
* is directed towards its principal focus.
* is parallel to its principal axis.
2.  If the image formed by a mirror for all positions of the object placed in front of it is always virtual and diminished, state the type of the mirror. Draw any ray diagram in support of your answer.
3. The linear magnification produced by a spherical mirror is +1/3+, Analysing this value, state the type of mirror and position of the object with respect to the pole of the mirror. Draw any diagram to justify your answer.
4. An object is kept at a distance of 4 m space, start text, m, end text in front of a spherical mirror, which forms its erect image at a distance of 1m, space, start text, m, end text from the mirror. What is the magnification? Is the mirror concave or convex?
5. The image of a candle flame placed at a distance of 30 cm, from a mirror is formed on a screen placed in front of the mirror at a distance of 60 cm, from its pole. What is the nature of the mirror? Find its focal length?​

Answer 1

Answer:

3.2 m away from a plane mirror . sita picks it up and places it on a chair that is 1 m away from the mirror [in the same straight line]. what is the distance between the mirror and new image
