Which of the following statements are correct?
(A) When light rays undergoes two internal reflections inside a raindrop, a secondary rainbow is formed.
(B) The angle between the emergent ray and angle of prism is called the angle of deviation.
(C) Light undergoes successive total internal reflections as it move through an optical fibre.
(D) A telescope provides angular magnification of distant objects.
(E) A simple magnifier is a diverging lens of small focal length.
Choose the correct answer from the options given below :

Answer & Solution
Correct Answer
(B) (A), (C) and (D) only
Step-by-step Solution
Detailed explanation
(A) Correct: A secondary rainbow is formed when light undergoes two internal reflections inside a raindrop. (A primary rainbow involves only one). (C) Correct: Optical fibers work on the principle of total internal reflection, allowing light to travel through the core by…
