A light ray is incident on air liquid interface at 45 degrees and is refracted at 30 degrees what is the refractive index of liquid?For what angle between refracted ray and refracted ray be 90 degrees?  
Asked by ranasiddusai630 | 18 Aug, 2019, 03:46: PM
answered-by-expert Expert Answer
Refractive index = sin(i)/sin(r) = sin45/sin30 = √2 = 1.414
 
where i is angle of incidence and r is angle of refraction.
 
Secon part of question :  " angle between refracted ray and refracted ray ? "   not able to understand
