Compton Wavelength Equation

A particle's Compton wavelength is equal to the wavelength of a photon with the same energy as the particle's mass. As a result, the conventional Compton wavelength equation is λ=h/mc

  • The Planck constant,h=6.62607*10-34J/s
  • λ be the wavelength
  • m be the mass of a particle
  • c be the speed of light, Its value is c=299792458 m/s

How to determine the Compton Wavelength

You can compute the Compton wavelength of a body by following the specified procedures.

  • Obtain the mass of the particle.
  • Substitute the values in the Compton wavelength equation is λ = h / (mc)
  • Do multiplication the mass of the body by the speed of light.
  • To determine the Compton wavelength, divide the constant by the product.

Compton Wavelength Examples

Question 1: How Do You find out the Compton Wavelength on an electron?


Consider the problem, we have

Mass of the particle, m = 9.15x10-31kg

h = 6.626x10³⁴J/s

We Know That,The Compton Wavelength Equation is λ=h/mc

Substitute the value, c=3x10 m/s in the above equation, we get

λ = (6.626x10-34)/((9.1x10-31)x(3x 10))

λ = 0.2427 Å

Therefore, The wavelength the Compton wavelength is 0.243 Å.

FAQs on Compton Wavelength Calculator

1. What's the Difference Between a Photon and an Electron?

An electron is a negatively charged particle that moves from the negative end to the positive end, whereas a photon is a massless particle that has no charge.

2. Is it possible for a photon to become an electron?

Yes! When a photon's energy is totally transferred into the mass of two particles, an electron and an anti-electron, the photon transforms into an electron.

3. What role does the Compton wavelength play?

Taking quantum physics and special relativity into account, the Compton wavelength represents a basic limitation on measuring a particle's position. This restriction is based on the particle's mass m.

4. What is the maximum Compton shift value?

When 1cos has the maximum value, which is for the angle =180°, the largest Compton shift occurs.

5. What is the wavelength equation of Compton?

The wavelength equation for Compton is = h/ (mc). Here, c is the speed of light, m is the particle's mass, h is the Planck constant, and is the particle's wavelength.
