Refraction At Spherical Surface MCQ - Practice Questions with Answers

A small object is embedded in a glass spher$\mathrm{e}(\mu=1.5)$ of radius 5cm at a distance 1.5cm left of the centre. The image of the object as seen by an observer standing to the left of the sphere is at a distance: 

A spherical surface of curvature R separates air $(\mu=1.5)$. The centre of curvature is in the glass. A point object $P$ placed in the air is found to have a real image $Q$ in the glass. The line $P Q$ cuts the surface at a point $O$ and $P O=O Q$. The distance $P O$ is equal to

A spherical convex surface separates object and image space of refractive index 1 and $4 / 3$ respectively. If the radius of curvature of the surface is 0.1 m, its power is :

A glass sphere $(\mu=1.5)$ of radius 8 cm is placed in sunlight. Where is the image of the sun formed by the light passing through the sphere? When refraction by first surface of sphere

A glass sphere $(\mu=1.5)$ of radius 8 cm is placed in sunlight. Where is the image of the sun formed by the light passing through the sphere? When refraction by second surface of sphere

Find the total number of candidates who appeared in all banking exams in 2020.

In the situation illustrated below, the object is set up 0.5 m away from a converging mirror. If the focal length of the lens is 0.2 m, determine a) the location of the real image, and b) the magnification of the image.

In the shown in the figure, find the position and size of the image for the situation.

What will be the magnification formula in the mentioned figure, where v = position of the image from the pole and u = position of the object from the pole?
