Question

calculate the de-Broglie’s wavelength of a mass 10^-10kg moving at a velocity 10^3cm/hour

Class11​

Answer 1

Answer:

Explanation:

λ=h/p

but p (i.e momentum)= mv

∴ λ= h/mv      (h=6.67×10⁻³⁴)

λ= 6.67×10⁻³⁴/ 10⁻¹⁰ × 10³

λ= 6.67×10⁻³⁴/10⁻⁷

λ= 6.67×10⁻³⁴⁺⁷/10

λ= 6.67×10⁻²⁷/10

λ= 6.67ₓ10⁻²⁸
