De Broglie Wavelength Solution

STEP 0: Pre-Calculation Summary

Formula Used

Wavelength = [hP]/Photon's Momentum
λ = [hP]/p
This formula uses 1 Constants, 2 Variables

Constants Used

[hP] - Planck constant Value Taken As 6.626070040E-34

Variables Used

Wavelength - (Measured in Meter) - Wavelength is the distance between identical points (adjacent crests) in the adjacent cycles of a waveform signal propagated in space or along a wire.
Photon's Momentum - (Measured in Kilogram Meter per Second) - Photon's Momentum is the quantity of motion that an photon has. Photon or Light indeed carries energy via its momentum despite having no mass.

STEP 1: Convert Input(s) to Base Unit

Photon's Momentum: 1000 Kilogram Meter per Second --> 1000 Kilogram Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

λ = [hP]/p --> [hP]/1000

Evaluating ... ...

λ = 6.62607004E-37

STEP 3: Convert Result to Output's Unit

6.62607004E-37 Meter -->6.62607004E-28 Nanometer (Check conversion here)

FINAL ANSWER

6.62607004E-28 ≈ 6.6E-28 Nanometer <-- Wavelength

What is De Broglie hypothesis?

De Broglie, in his 1924 PhD thesis, proposed that just as light has both wave-like and particle-like properties, electrons also have wave-like properties.

How to Calculate De Broglie Wavelength?

De Broglie Wavelength calculator uses Wavelength = [hP]/Photon's Momentum to calculate the Wavelength, The De Broglie Wavelength formula is defined as the wavelength, λ, associated with a massive particle (i.e., a particle with mass, as opposed to a massless particle) and is related to its momentum, p, through the Planck constant, h. Wavelength is denoted by λ symbol.

How to calculate De Broglie Wavelength using this online calculator? To use this online calculator for De Broglie Wavelength, enter Photon's Momentum (p) and hit the calculate button. Here is how the De Broglie Wavelength calculation can be explained with given input values -> 6.6E-19 = [hP]/1000.

FAQ

What is De Broglie Wavelength?

The De Broglie Wavelength formula is defined as the wavelength, λ, associated with a massive particle (i.e., a particle with mass, as opposed to a massless particle) and is related to its momentum, p, through the Planck constant, h and is represented as λ = [hP]/p or Wavelength = [hP]/Photon's Momentum. Photon's Momentum is the quantity of motion that an photon has. Photon or Light indeed carries energy via its momentum despite having no mass.

How to calculate De Broglie Wavelength?

The De Broglie Wavelength formula is defined as the wavelength, λ, associated with a massive particle (i.e., a particle with mass, as opposed to a massless particle) and is related to its momentum, p, through the Planck constant, h is calculated using Wavelength = [hP]/Photon's Momentum. To calculate De Broglie Wavelength, you need Photon's Momentum (p). With our tool, you need to enter the respective value for Photon's Momentum and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
