Question

De Broglie equation is:

• A. $\lambda =\frac{mv}{h}$
• B. $\lambda =hmv$
• C. $\lambda =\frac{hv}{m}$
• D. $\lambda =\frac{h}{mv}$

Answer 1

The correct option is D $\lambda =\frac{h}{mv}$

The de Broglie equation relates a moving particle's wavelength with its momentum. The de Broglie wavelength is the wavelength, λ, associated with a massive particle and is related to its momentum, p, through the Planck constant, h as:

$\lambda =\frac{h}{mv}$
