Physics - Geometrical Optics Question with Solution | TestHub

A small rod ABC is put in water $\left({\mathrm{n}}_{\mathrm{w}}=\frac{4}{3}\right)$ making an angle 6° with vertical. If it is viewed paraxially from above, it will look like bent shaped ${\mathrm{ABC}}^{\prime }$. The angle of bending ( $\angle \mathrm{CBC}$ ') is given by ${\alpha }^{\circ }$. Find the value of $2\alpha$.
