Question:

If the momentum of a particle increases, what happens to its de Broglie wavelength ?

Options:

It remains the same

It decreases

It increases

It decreases for lower frequencies only.

Correct Answer:

It decreases

Explanation:

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

Debroglie wavelength is inversely propotional to momentum . As momentum increases debroglie wavelength decreases.
