Question

3. Why does the transmission electron microscope make it possible to see more detailed images than those in the 17th century? a. Because the electrons used in TEM move at high speeds, facilitating good resolution. b. Because the light used in TEM moves at high speeds, facilitating good resolution. c. Because the electrons used in TEM are associated with very short wavelengths at high speeds, facilitating good resolution. d. Because the lens used in TEM has high numerical aperture, facilitating good resolution e. Because the vacuum increases resolution.

Explanation / Answer

c. Because the electron used in TEM are associated with very short wavelength at high speed, facilitating good resolution

Transmission electron microscope is capable of imaging at a higher resolution than those in 17 century because of TEM microscope shows the smaller de Broglie wavelength of the electron. This enables the instrument to capture fine detail.

A good microscope is that which has a shorter wavelength of the electron than the visible light so it can capture a good image.
