Define resolving power of a compound microscope. How does the resolving power of a compound microscope change when : (i) refractive index of the medium between the object and objective lens increases, (ii) wavelength of the radiation used is increased? |

Answer» SOLUTION :For definition of resolving POWER of a compound microscope (i) If the REFRACTIVE index (n) of the medium between the object and objective lens increases, the resolving power increases because resolving power `mu` N.A. (ii) On increasing the wavelength of radiation used, the resolving power of microscope decreases because resolving power `PROP(1)/(lamda)`. |
