Question

5. An electron microscope uses electrons accelerated by a voltage of 50 kV, how does the resolving power of this electron microscope compare with that of an optical microscope which uses yellow light?

Options -

(1) 104 times (2) 105 times (3) 106 times (4) 103 times​

Answer 1

Dual Nature of Radiation and Matter. An electron microscope uses electrons accelerated by a voltage of 50 kV. ... Since the wavelength of yellow light is 5.99 x 10–7 m, so it follows that electron microscope will have resolving power 105 times that of optical microscope
