A light ray incident on a plane interface of an irregular glass slab (refractive index\[=\surd 2\]) at an angle of incidence\[45{}^\circ \], Angle of inclination of this interface is\[60{}^\circ \]. Its other interface is curve of (radius of curvature\[=0.4\text{ }m\]). The ray after entering into another medium \[\left( {{\mu }_{3}}=1.514 \right)\]meets principal axis PQ at E as shown in the figure. Find distance OE (in meter)
