electrons in an electron microscope are accelerated form rest to a momentum making their wavelength 0.06 nm.(adsbygoogle = window.adsbygoogle || []).push({});

1. what is the voltage Vo needed for this?

2. What is the final electron velocity?

For 1.

[tex]E=\frac{hc}{\lambda}=\frac{1240eVnm}{0.06 nm}[/tex]

solve for E

For 2.

[tex]E=.5mv^2[/tex]

Solve for v plugging in E from #1 and m=mass of electron

is this the correct thought process?
