Question

Q10) Calculate the momentum of a particle which has a de Broglie wavelength of 1×10^-10m

Answer 1

Answer:

Explanation:

De Broglie wavelength=Planck constant/Momentum

So, momentum is (6.63*10^-34)/(1*10°-10) calculate this, you will get the answe

Answer 2

Given :

• De Broglie wavelength = 1×10⁻¹⁰ m.

$\rule{150}{2}$

To Find :

We have to find the momentum of the particle.

$\rule{150}{2}$

Solution :

We know that,

⇒ Wave length = Plank's Constant/Momentum

→ Momentum = Plank's Constant/Wave Length

→ Momentum = 6.63×10⁻³⁴/1×10⁻¹⁰

→ Momentum = 6.63×10⁻²⁴

∴ Momentum is 6.63×10⁻²⁴ m
