1.	Define resolving power of microscope. How does it affect when:(i) Wavelength of illuminating radiation decreases?(ii) Diameter of object lens decreases? Give explanation of your answer.
Answer» The resolving power of a microscope is defined as reciprocal of the smallest distance between two point objects at which they can be just resolved when seen through the microscope. R.P. of a microscope = \(\frac{1}{d}=\frac{2 n \sin \theta}{\lambda}\) (i) As R.P. ∝ \(\frac{1}{\lambda}\) When λ decreases, R.P. increases. (ii) When the aperture of the objective lens decreases, the semivertical angle θ decreases and hence the resolving power of the microscope increases.
