Question

Two particles have equal momenta. What is the ratio of their de-broglie wavelengths?

Answer 1

The ratio of the debroglie wavelengths will be 1:1

Explanation,

We know that the wavelength will be given by the relation,

λ = $\frac{h}{p}$

where h = planks constant

p = momentum

Since h is constant for all particle, hence as long as the momentum of 2 particles will remain same they will always produce same wavelength.

Hence the ratio of the debroglie wavelengths will be 1:1 .
