Chapter 2. Structure of Atom

Answer 1

λ = h/mv, where λ is wavelength, h is Planck's constant, m is the mass of a particle, moving at a velocity v. de Broglie suggested that particles can exhibit properties of waves.

λ=(6.626*10^-34)/{(0.1)*(10)}

λ=6.626*10^-34 meter

Orλ= 6.626*10^-24 angstorm.
