JEE Main 2023 (Online) 11th April Evening Shift Physics - Geometrical Optics Question 56 English Explanation

 Apparent depth of O=dμ\text { Apparent depth of } \mathrm{O}=\frac{\mathrm{d}}{\mu} =843=6 cm=\frac{8}{\frac{4}{3}}=6 \mathrm{~cm}

Distance of object from mirror = 42 + 6 = 48 m

 Distance between O and I2=48+50=98 cm\text { Distance between } \mathrm{O} \text { and } \mathrm{I}_2=48+50=98 \mathrm{~cm}
