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.

Options

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

d.

Explanation

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
