Q1Ray Optics Core Principles

Expected: 60sEasy

A microscope has an objective of focal length 2 cm , eyepiece of focal length 4 cm and the tube length of 40 cm . If the distance of distinct vision of eye is 25 cm , the magnification in the microscope is

Q2Ray Optics Advanced Applications

Expected: 60sEasy

An object is placed at a distance of 40 cm from a concave mirror of focal length 15 cm. If the object is displaced through a distance of 20 cm towards the mirror, the displacement of the image will be

Q3Ray Optics Problem Solving Techniques

Expected: 60sEasy

The refractive index of the material of a prism is $\sqrt 2$ and the angle of the prism is 30°. One of the two refracting surfaces of the prism is made a mirror inwards, by silver coating. A beam of monochromatic light entering the prism from the other face will retrace its path (after reflection from the silvered surface) if its angle of incidence on the prism is
