Can you solve this JEE Advanced Question? Optics+ Differential Calculus

Full detailed solution here: https://youtu.be/IvsDdpVIG9o

A beam of polychromatic light passes through a thin prism of prism angle 6°. The refractive index
of the material of the prism varies with wavelength (𝜆) as 𝑛(𝜆)=𝛼𝜆 +𝛽
𝜆2
, where 𝛼=3 𝜇m−1 and
�
�=0.096 𝜇m2. If 𝜆min is the wavelength at which the angle of minimum deviation 𝐷𝑚 is
smallest, then the correct value of 𝐷𝑚 at 𝜆min is
