A single slit is illuminated by light of wavelengths λa and

A single slit is illuminated by light of wavelengths λa and λb chosen so that the first diffraction minimum of the λab component coincides with the second minimum of the λb component.

(a) If λb = 350nm, what is λa? For what order number mb (if any) does a minimum of the λb component coincide with the minimum of the λa component in the order number

(b) ma = 2 and
