Question

Amajor breakthrough in the studies of cells came with the development of electron microscope. This is because

(a) the resolving power of the electron microscope is 200-350 nm as compared to 0,1 -0.2 for the light microscope 

(b) electron beam can pass through thick materials, whereas light microscopy required thin sections 

(c) the electron microscope is more powerful than the light microscope as it uses a beam of electrons which has wavelength much longer than that of photons 

(d) the resolution power of the electron microscope is much higher than that of the light microscope

Answer 1

Correct option (d) the resolution power of the electron microscope is much higher than that of the light microscope

Explanation:

The resolution power of the electron microscope rs much higher than that of the light microscope.

As an average the resolving power of a light microscope is 0.25 μm-0.3 gm while that of electron microscope is 2-10 Å though theoritically, it is 0.25 Å  The magnification range of light microscope is 2000-4000 while of electron microscope is 100000-300000.
