Question

Which of the following expressions gives the de Broglie relationship?

(a) \(\frac h{mv} = p\)

(b) \(\lambda = \frac h{mv}\)

(c) \(\lambda = \frac h{mp}\)

(d) \(\lambda _m = \frac vp\)

Answer 1

Correct option is (b) \(\lambda = \frac h{mv}\) 

The wavelength of the matter wave associated with a particle in motion is given by λ = h/p; p = mv (momentum)
