G i v e n colon space minus mu presubscript w subscript g equals mu subscript g over mu subscript w equals 3 over 2 subscript w mu subscript a l end subscript equals mu subscript a l end subscript over mu subscript w equals 4 over 3 rightwards double arrow mu subscript w over mu subscript a l end subscript equals 3 over 4 T o space f i n d space minus space subscript a l end subscript mu subscript g C a l c u l a t i o n s space minus space subscript a l end subscript mu subscript g equals mu subscript g over mu subscript a l end subscript equals mu subscript g over mu subscript w cross times mu subscript w over mu subscript a l end subscript equals 3 over 2 cross times 3 over 4 equals 9 over 8 equals 1.125 space  
 
Thus, 
Refractive index of glass w.r.t. alcohol is 9/8 or 1.125
