[amp_mcq option1=”Hyperbolic path along the axis” option2=”Parabolic path along the axis” option3=”Helical path” option4=”Path where rays changes angles at core-cladding interface” correct=”option3″]
The correct answer is: C. Helical path.
A skew ray is a ray that does not pass through the optical axis of a lens or mirror. It will therefore be refracted or reflected at an angle to the optical axis. The path of a skew ray can be described as a helical path, with the ray spiraling around the optical axis as it passes through the lens or mirror.
The other options are incorrect because:
- A hyperbolic path is the path of a ray that is refracted or reflected by a concave lens or mirror.
- A parabolic path is the path of a ray that is refracted or reflected by a convex lens or mirror.
- A path where rays changes angles at core-cladding interface is the path of a ray that passes through the core and cladding of an optical fiber.
