Question

NOTE: Q.No 17-20 contains four sub-parts each. You are expected to answer all
four sub-parts in these questions.
Read the following and answer the questions given below
We can study the formation of image by a spherical mirrore by drawing ray diagrams
It is more convenient to consider only
two rays for the sake
of clarity of the ray
reflection from the mirror. The intersection of at least two reflected rays give the
position of the image of an object.
1) An object is kept at a distance more than twice the focal length from a concave
mirror. The image will be formed:
a) at F b) Beyond C
c) At C
d) None of these
ii) The nature of the image is not effected by the position of the object in
a) only convex mirror
b) only plane mirror
c) both convex and careere mirror
plane
d) only concave mirror
111) The angle of reflection in the given figure is
P
a) 900
b) 00
c) 1800
d) none of these
iv)The sign convention for focal length of a concave mirror is
a) positive
b) negative
c) can be positive or negative depending on position of the object,
d) none of these​
