A light ray passing along the principal axis of a lens is
Show Hint
A light ray passing along the principal axis of a lens remains undeviated, unlike rays passing at angles that get refracted.
Updated On: Apr 17, 2025
- Deviated
- Reflected
- Refracted
- Undeviated
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
When a light ray passes along the principal axis of a lens, it passes straight through without being deviated or refracted. Therefore, the correct answer is "Undeviated."

- A beam of light coming from a distant source is refracted by a spherical glass ball (refractive index 1.5) of radius 15 cm. Draw the ray diagram and obtain the position of the final image formed.
- A double convex lens of glass has both faces of the same radius of curvature 17 cm. Find its focal length if it is immersed in water. The refractive indices of glass and water are 1.5 and 1.33 respectively.
- A point source is placed at the bottom of a tank containing a transparent liquid (refractive index \( n \)) to a depth H. The area of the surface of the liquid through which light from the source can emerge out is:
- Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A) : If Young’s double slit experiment is performed in an optically denser medium than air, then the consecutive fringes come closer.
Reason (R) : The speed of light reduces in an optically denser medium than air while its frequency does not change.
In the light of the above statements, choose the most appropriate answer from the options given below : - A plane wave travelling in a medium is incident on a plane surface separating this medium from a rarer medium. Draw a diagram to show refraction of the wave. Hence, verify Snell’s law.
