1.	Following table gives the numerical value of absolute refractive indices of several transparent media. {:("Transparent medium","Refractive Index","Transparent medium","Refractive index"),("Free space",1.000,"Canada balsam",1.53),("Air",1.0003,"Rock salt",1.54),("Ice",1.31,"Carbon disulphide",1.63),("Water",1.33,"Dense flint glass",1.65),("Alcohol",1.36,"Ruby",1.71),("Kerosene",1.44,"Sapphire",1.77),("Turpentine oil",1.47,"Diamond",2.42),("Crown glass",1.52,,):} Relative refractive index of Ruby with respect to alcohol is
Answer» 1.71 1.36 `(1.36)/(1.71)` `(1.71)/(1.36)` Solution :Relative REFRACTIVE index of RUBY w.r.t. ALCOHOL `= ("Refractive index of Ruby")/("Refractive index of Alcohol") = (1.71)/(1.36)`
