Vedclass · Answer

(A) The resolving power $(R.P.)$ of a microscope is inversely proportional to the wavelength $(\lambda)$ of the radiation used $(R.P. \propto 1/\lambda)$.In an electron microscope, an electron beam is used, which has a very small de Broglie wavelength $(\lambda \approx 1 	ext{ \AA})$.In an optical microscope, visible light is used, which has a much larger wavelength $(\lambda \approx 5000 	ext{ \AA})$.Since the wavelength of the electron beam is approximately $5000$ times smaller than that of visible light, the resolving power of an electron microscope is approximately $5000$ times greater than that of an optical microscope.
