Embibe Experts Solutions for Chapter: Ray Optics, Exercise 14: Exercise (Analytical Questions)

A clear transparent glass sphere ($\mu$ = 1.5) of radius R is immersed in a liquid of refractive index 1.25. A parallel beam of light incident on it will converge to a point. The distance of this point from the centre will be

A point object is placed at a distance of $20 \mathrm{cm}$ from a thin plano-convex lens of focal length $15 \mathrm{cm}$. If the $B$ plane surface is silvered, the image will from at

A film projector magnifies a film of area $100$ square centimeters on screen. If linear magnification is $4$, then the area of the magnified image on the screen will be

For the given incident ray as shown in the figure, the condition of total internal reflection of this ray the minimum refractive index of the prism will be:-

A bulb is located on a wall. Its image is to be obtained on a parallel wall with the help of convex lens. If the distance between parallel walls is 'd’ then required focal length of lens placed in between the walls is:-

A short linear object of length $L$ lies on the axis of a spherical mirror of focal length $f$ at a distance $u$ from the mirror. Its image has an axial length $L\text{'}$ equal to

An object is placed at a distance of 10 cm from a co-axial combination of two lenses A and B in contact. The combination forms a real image three
times the size of the object. If lens B is concave with a focal length of 30 cm, the nature and focal length of lens A is

White light is incident on the face $AB$ of a glass prism. The path of the green component is shown in the figure. If the green light is just totally internally reflected at the face $AC$ as shown, the light emerging from the face $AC$ will contain
