1.	A ray of light is incident on the interface between water and glass at an angle `i` and refracted parallel to the water surface, then value of `mu_(g)` will be A. `(4//3)sini`B. `1/(sin i)`C. `4/3`D. `1`
Answer» (b) `._(g)mu_(w)=(sin i )/(sin r)` `._mu_(a)=(sin r)/(sin 90^(@))` `implies ._(g)mu_(w)xx._(w)mu_(a)=(sin i)/(sin r)=(sin r)/(sin 90^(@))=sini` or `(mu_(w))/(mu_(g))xx(mu_(a))/(mu_(w))=sin i impliesmu_(g)=1/(sin i)`
