Question

The expression for de Broglie wavelength is :

• A. $p=\frac{h}{\lambda }$
• B. $p=\frac{h}{2\lambda }$
• C. $p=\frac{2\pi }{h\lambda }$
• D. $p=\frac{2\pi }{\lambda }$

Answer 1

The correct option is A $p=\frac{h}{\lambda }$

De Broglie wavelength is given by $\lambda =\frac{h}{p}$, whrer p is the momentum

or, $p=\frac{h}{\lambda }$
