What is the wavelength of a photon that has the same momentum as an electron moving with a speed of 1500 m/s? express your answer using two significant figures

Sagot :

The wavelength of photon in 2 significant is 4.8 × 10∧3 angstrom

Given: Mass of photon= Mass of electron= 9.11×10^-31 kg

            Velocity= 1500m/s

            Planck constant(h)= 6.6261*10^-34 Js

            λ= h/mv=  6.6261*10^-34 Js/(9.11×10^-31× 1500)kgm/s

               = 4.8 × 10^3 angstrom

About De-brogile wavelength:

De Broglie stated that every particle could be described as having a particular wavelength and formulated the famous de Broglie equation.

De Broglie asserts that a beam of particles with a certain mass can act like a matter wave. The particle's mass and velocity are related to its wavelength:

λ= h/mv, where,

  • m is the particle's mass.
  • v represents the particle's speed.
  • The Planck constant, or h, has a value of 6.6261*10^-34 Js.
