Answer
blue light
Work Step by Step
We know that $\theta_{min}=1.22\frac{\lambda}{D}$. This equation shows that the angular separation is directly proportional to the wavelength. This shows that with an increase in wavelength, the angle of separation increases and as a result, the resolution of the light decreases. Thus, we will have a greater resolution for the smaller wavelengths than the larger wavelengths and hence blue light has the greater resolution.
