Which of the following statements are correct?
(A) Total internal reflection occurs when a ray of light travels from a rarer transparent medium to a denser medium.
(B) In total internal reflection, the incident ray of light remains in the same medium after reflection.
(C) In total internal reflection, the angle of incidence inside the denser transparent medium is equal to the angle of reflection in the same medium.
(D) In total internal reflection inside a denser medium there is no angle of refraction
Choose the correct answer from the options given below:
- A (B) and (C) only
- B (A) and (B) only
- C (B), (C) and (D) only
- D (C) and (D) only
Answer & Solution
Correct Answer
(C) (B), (C) and (D) only
Step-by-step Solution
Detailed explanation
Statement (B) is correct: Total internal reflection is a type of reflection, so the light remains in the same medium. Statement (C) is correct: The law of reflection (\( \theta_i = \theta_r \)) applies to all reflections, including total internal reflection. Statement (D) is…
