Given below are two statements : Statement I : If the Brewster's angle for the light propagating from air to glass is θ B , then Brewster's angle for the light propagating from glass to air is π 2 - θ B . Statement II : The Brewster's angle for the light propagating from glass to air is tan - 1 μ g , where μ g is the refractive index of glass. In the light of the above statements, choose the correct answer from the o
Options
- ABoth Statements I and Statement II are true.
- BStatement I is true but Statement II is false.
- CBoth Statement I and Statement II are false.
- DStatement I is false but Statement II is true.
Correct answer
B. Statement I is true but Statement II is false.
Step-by-step solution
Applying Snell's law, we get μ a sin i = μ g sin 90 ° - i tan i = μ g μ a When going from glass to air tan i ' = μ a μ g = cot i Clearly, i ' = π 2 - i & hence Statement I is true but Statement II is false.
