Question:

A particle is dropped from height H. The de Broglie wavelength of the particle as a function of height is proportional to :

Options:

H¹

H⁰

H^1/2

H^-1/2

Correct Answer:

H^-1/2

Explanation:

Velocity acquired by a aprticle while falling from height H is : v = \(\sqrt { 2gH}\)

\(\lambda\) = \(\frac{h}{mv}\)

∴ λ ∝ H^-1/2
