Problem
An experimenter plots the de Broglie wavelength λ of electrons (accelerated through a potential difference V) on the y-axis against 1/V on the x-axis and obtains a straight line through the origin. Which fundamental constant can be evaluated from the slope of this line? Briefly give the reason for your choice.
