Question

calculate the momentum of a moving particle whose wavelenth is 1 nm​

Answer 1

Explanation:

De Broglie wavelength = 1nm = 10^-9 m

plank's constant= 6.62× 10^-34 m

hence, formula applied :-

wavelength= plank's constant / momentum

so, momentum= plank's constant/ wavelength

so,. 6.62×10^-34/ 10^-9

so,. 6.62 × 10^-25 ( answer )

Answer 2

Hey Sister ! 1 of the Best JEE MAINS question ☺✌

Given - Momentum=1nm

✔✅ Solution -

De Broglie Wavelength = 1nm

= 10^-9m

Max Plank' Constant = 6.625 × 10^ -34m

☆FORMULA APPLIED :- WAVELENGTH = PLANK'S CONSTANT / MOMENTUM

So, 6.625×10^ -34 / 10^ -9

☆ = 6.625 × 10^ -25

!!Hope It helped!!
