A prism of refractive index n1 and another prism of refractive index n2 are stuck together (as shown in the figure). n1 and n2 depend on \(\lambda\), the wavelength of light, according to the relation
\({n_1} = 1.2 + {{10.8 \times {{10}^{ - 14}}} \over {{\lambda ^2}}}\) and \({n_2} = 1.45 + {{1.8 \times {{10}^{ - 14}}} \over {{\lambda ^2}}}\)
The wavelength for which rays incident at any angle on the interface BC pass through without bending at that interface will be _____________ nm.
