A ray of unpolarised light is incident on the glass surface of refractive index \(1 \cdot 73\) at
polarizing angle. The angle of refraction will be [Take \(\left.\tan 60^{\circ}=1 \cdot 73\right]\)
- A \(45^{\circ} .\)
- B \(15^{\circ} .\)
- C \(35^{\circ} .\)
- D \(30^{\circ} .\)
Answer & Solution
Correct Answer
(D) \(30^{\circ} .\)
Step-by-step Solution
Detailed explanation
\(\therefore 1.73=\tan i\)
\(\quad \therefore i=60^{\circ}\) \(\mu=\tan i_{p}\)
\(\therefore r=30^{\circ}\) \(i+r=90^{\circ} \therefore\)
\(\quad \therefore i=60^{\circ}\) \(\mu=\tan i_{p}\)
\(\therefore r=30^{\circ}\) \(i+r=90^{\circ} \therefore\)
