Which graph gives the dependence of 1/λ² on kinetic energy E for the de Broglie wavelength of a free nonrelativistic particle? [Image]

G1 Physics · Accepted Answer

λ = h/√(2mE). Squaring gives 1/λ² = (2m/h²)E, so 1/λ² is directly proportional to E; its graph is a straight line through the origin. Answer: C.
