What is the de Broglie wavelength of a 300-g object moving at a velocity of 50 m/s (about 100 mph)? A)4 × 10^-38 m B)4 × 10^-35 m C)4 × 10⁹ m D)4 × 10¹² m

Question

Quizplus · Accepted Answer

The de Broglie wavelength is given by the formula λ = h/mv, where h is Planck's constant, m is the mass of the object, and v is its velocity. Substituting the given values, we get λ = 6.626 x 10^-34/[(300/1000) x 50] = 4 x 10^-35 m, which is closest to option B.
