Question

Statement I: A ray is incident from outside on a glass sphere surrounded by air as shown in Figure. This ray may suffer total internal reflection at the second interface.

Statement II: For a ray going from a denser to rarer medium, the ray may suffer total internal reflection.
A. Statement is True, Statement II is True, Statement II is correct explanation for Statement I
B. Statement I is True, Statement II is True, Statement II is NOT a correct explanation for Statement I.
C. Statement I is True, Statement II is False.
D. Statement I is False, Statement II is True.

Answer 1

Correct Answer - d.
From symmetry, the ray shall not suffer TIR at second interface, because the angle of incidence at first interface equals to angle of emergence at second interface. Hence, Statement I is false
