3D.3 Flashcards
1
Q
what scattering angle do electrons have the highest scattering density
A
50
2
Q
what is the equation to find the wavelength of an electron
A
wave lenght = h/p
3
Q
what is the mass of an electron
A
9.11 x 10^-31
4
Q
what is a safety note that we should have when operating with an electron beam tube
A
operate with shrouded connection to minimize electric shock
5
Q
how can the wavelength of an electron be altered
A
by changing the voltage applied to accelerate it
6
Q
electron ability to act as a wave and have its wavelength altered helps with?
A
microscopy as we can change the electron wavelength to be much smaller than light giving us a bigger image
7
Q
why is altering the wavelength helpful in microscopy
A
any mini-sized object can be imagined by wave with the same wavelength as it
