Question

The polarizing angle of glass is ${57}^{\circ }$. A ray of light which is incident at this angle will have an angle of refraction as

• A. ${43}^{\circ }$
• B. ${25}^{\circ }$
• C. ${38}^{\circ }$
• D. ${33}^{\circ }$

Answer 1

The correct option is D

${33}^{\circ }$

we know that,

${\theta }_p+r={90}^{\circ }$

$r=90-57={33}^{\circ }$
