The de-Broglie wavelength - Vidyadip

MCQ

The de-Broglie wavelength $\lambda$

A
is proportional to mass
B
is proportional to impulse
✓
Inversely proportional to impulse
D
does not depend on impulse

✓

Answer

Correct option: C.

Inversely proportional to impulse

The De-Broglie wavelength is $\lambda=\frac{h}{|p|}=\frac{h}{|I|} \Rightarrow \lambda \propto \frac{1}{|I|}$
