Question

5. Read the following and answer four question from 5 (i) to 5 (v)

Lens is a piece of transparent glass bound by two spherical surfaces. They
are of two types: conver lenge and concave lens. The lens formula is given by 1/f=1/v=
1/4 where 4 is object distance, vis image distance and fis focal length, focal length of
conven lens is positive where as focal length concave lens is negative. The linear magnifi-
cation produced by lens is equal to the ratio of image distance to the object distance. If the
magnification has positive value, The image is virtual and erect and if the magnification has
negative value the image will be real and inverted.
5(1) The following figure shows the path of light ray through three lenses marked
L, L, and L, and their focal points F, F, and F, respectively. Out of LL
and L, concave lens is/are​
