- ✓$\ce{NiFe_2O_4}$
- Dnickel
✓
Answer
Correct option: C.
$\ce{NiFe_2O_4}$
In cassette player, materials used for magnetic tapes is $\ce{NiFe_2O_4}$.

For an isosceles prism of angle $A$ and refractive index $\mu$, it is found that the angle of minimum deviation $\delta_m=A$. Which of the following options is/are correct?
→[$A$] At minimum deviation, the incident angle $i_1$ and the refracting angle $r_1$ at the first refracting surface are related by $\mathrm{r}_1=\left(\mathrm{i}_1 / 2\right)$.
[$B$] For this prism the refractive index $\mu$ and the angle of prism $A$ are related as $A=\frac{1}{2} \cos ^{-1}(\mu / 2)$.
[$C$] For this prism, the emergent ray at the second surface will be tangential to the surface when the angle of incidence at the first surface is $i_1=\sin ^{-1}\left[\sin A \sqrt{4 \cos ^2 \frac{A}{2}-1}-\cos A\right]$.
[$D$] For the angle of incidence $i_1=A$, the ray inside the prism is parallel to the base of the prism.
