501: The resolving power of an electron microscope is much higher than that of an ordinary light microscope because resolving power increases:
(a) If wavelength is short and wavelength of electron beam can be made quite small by accelerating the electrons.
(b) If wavelength is short and light given by electrons has very short wavelength.
(c) If magnification is high and electronic lens provides much higher magnification.
(d) If magnification is high and the electron microscope has a battery of lenses to provide high magnification.
502: Assertion (A):
