Frgan var: Berkna de Broglie-vglngden fr en elektron som har hastigheten 1,5106 m/s. Jag svarade: Vi behver anvnda oss av de Broglies vglngdsformel = h / p dr: = vglngden h = Plancks konstant (6,62607015 10-34) p = elektronens rrelsemngd Vi behver utg frn det vrde som vi har, nmligen hastigheten. Rrelsemngd = massa x hastighet. En elektrons massa r 9,10938356 10^-31 kg. p = (9,10938356 10^-31) x (1,5 x 106) = 1,366407534 x 10^-24 = 6,62607015 10^-34 / 1,366407534 x 10^-24 = 5 x 10^-10 meter Eller 0,5 nm. Vad tror du
