Vedclass · Answer

(C) The accuracy of determining the position of an object using a beam of light is limited by the phenomenon of diffraction.According to the Rayleigh criterion,the resolving power of an optical system is inversely proportional to the wavelength of the light used.Mathematically,the limit of resolution or the minimum resolvable distance $d$ is given by $d \approx \frac{\lambda}{2 \cdot NA}$,where $\lambda$ is the wavelength and $NA$ is the numerical aperture.To achieve maximum accuracy,the minimum resolvable distance $d$ must be as small as possible.Since $d \propto \lambda$,a smaller wavelength $\lambda$ results in higher accuracy.Therefore,the maximum accuracy is achieved if the light is of shorter wavelength.
