1.	Ordinary light incident on a glass slab at the polarising angle suffers a deviation of ` 22^(@)`. In this case, the angle of refraction isA. `56^@`B. `34^(@)`C. `68^(@)`D. `22^@`
Answer» Correct Answer - B `delta=i-r=22^(@)` but `i+r=90^(@)` ` :. (i+r)-(i-r)=90^(@)-22^(@)` `:. 2r=68^(@) " " :. r=34^(@)`
