1. At what speed is an electron's de Broglie wavelength:
(a) 1.0 pm
(b) 1.0 nm
(c) 1.0 [tex]\mu[/tex]m
(d) 1.0 mm
2. [tex]\lambda[/tex] = [tex]\frac{h}{mv}[/tex]
3. I have solved for v, and I plugged in values, it gives me, for a = 4.54 x 10^(27) m/s, the ANSWER is: 2.77 x 10^(8) ms, it's way off, I tried converting energy into Js it also did not work, what am I overlooking?
