Q: What is the correct answer for CUET UG Physics Q44?

The correct answer is b. Let's evaluate each statement: (A) When light rays undergo two internal reflections inside a raindrop, a secondary rainbow is formed. This statement is **correct**. A primary rainbow results from one internal reflection, while a secondary rainbow is formed by two internal reflections within raindrops. (B) The angle between the emergent ray and angle of prism is called the angle of deviation. This

Let's evaluate each statement:
(A) When light rays undergo two internal reflections inside a raindrop, a secondary rainbow is formed. This statement is **correct**. A primary rainbow results from one internal reflection, while a secondary rainbow is formed by two internal reflections within raindrops.
(B) The angle between the emergent ray and angle of prism is called the angle of deviation. This statement is **incorrect**. The angle of deviation is the angle between the *incident ray* and the *emergent ray* when both are extended. The 'angle of prism' is the angle between the two refracting faces of the prism.
(C) Light undergoes successive total internal reflections as it moves through an optical fiber. This statement is **correct**. Optical fibers work on the principle of total internal reflection, effectively guiding light over long distances.
(D) A telescope provides angular magnification of distant objects. This statement is **correct**. The primary function of a telescope is to increase the apparent angular size of distant objects, thus providing angular magnification.
(E) A simple magnifier is a diverging lens of small focal length. This statement is **incorrect**. A simple magnifier (magnifying glass) is a **converging** (convex) lens, not a diverging lens. Its purpose is to produce an enlarged virtual image. Based on this analysis, statements (A), (C), and (D) are correct. This corresponds to option (b).
