What is the de broglie wavelength of a red blood cell, with mass 1.00 x 10-11 g, that is moving with a speed of 0.400 cm/s?

We have a formula for finding the de Broglie wavelength. The formula is written below:

λ = h/mv

where

h is the Planck's constant = 6.626*10⁻³⁴ J·s

m is the mass

v is the velocity

Substituting the values,

λ = 6.626*10⁻³⁴ J·s / (1.00 x 10-11 g) (1 kg/1000 g) * (0.400 cm/s) (1 m/100 cm)

λ = 1.66*10⁻¹⁷ m
