Question:

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:

Options:

(B) and (C) only

(A) and (B) only

(B), (C) and (D) only

(C) and (D) only

Correct Answer:

(B), (C) and (D) only

Explanation:

The correct answer is Option (3) → (B), (C) and (D) only

Analysis of the statements:

(A) False — Total internal reflection occurs when light travels from a denser medium to a rarer medium.

(B) True — In total internal reflection, the ray remains in the same (denser) medium after reflection.

(C) True — The angle of incidence equals the angle of reflection (law of reflection holds).

(D) True — For total internal reflection, refraction does not occur; the refracted ray disappears.

Correct statements: (B), (C), and (D)
