Monochromatic light rays parallel to x-axis strike a convex lens AB of refractive index `0.5`. If the lens oscillates such that AB tilts upto a small angle `theta` (in radian) on either side of y-axis, then find the distance between extreme positions of oscillating image:

A

`fsectheta`

B

`fsec^(2)theta`

C

`f(sectheta-1)`

D

The image will not move

Monochromatic light rays parallel to the principal axis (the x axis) are incident on a convex lens of focal length f. If the lens oscillates such that it tilts up to a small angle theta on either side of the y axis, then find the distance between the exterme positions of the image. Take sec theta ~~ 1 + (theta^(2))/(2) for small theta .

Fig. shows an equiconvex lens (of refractive index 1.5 ) in contact with a liquid layer on top of a plane mirror. A small needle with its tip on the principal axis is moved along the axis until its inverted image is found at the position of the needle. The distance of the needle from the lens is measured to be 45.0 cm . The liquid is removed and the experiment is repeated. The new distance is measured to be 30.0 cm . What is the refractive index of the liquid ?
