De Broglie Equation question
The correct answer to this question is C. Why is B wrong?

The value of planks constant is worked out using the formulae E=hf (planks equation). The 'h' is the constant of proportionality.
The de Broglie equation is an equation used to describe the wave properties of matter, specifically, the wave nature of the electron. He suggested that particles can exhibit properties of waves. The equation is the substitution of einsteins equation E=mc^2 into planks equation and shows us that wavelength is indirectly proportional momentum.
Ofcourse given momentum and wavelength you can work out planks constant but this is not what the equation describes. To accurately measure planks constant you plot E and f and work out the gradient which is the constant of proportionality 'h'.
