# What is the de Broglie wavelength of a proton?

## What is the de Broglie wavelength of a proton?

λ=hp=6.63×10−34 J ⋅ s(3 kg)(10 m/s)=2×10−35 m λ = h p = 6.63 × 10 − 34 J ⋅ s ( 3 kg ) ( 10 m/s ) = 2 × 10 − 35 m .

## Can a proton have a de Broglie wavelength?

Now in the question it is stated that a proton and electron have the same de broglie wavelength. If a proton and electron have the same de broglie wavelength their momentum will be equal. Hence the correct answer is option (A) Momentum of electron = momentum of proton.

What is the de Broglie wavelength of an electron which moves?

Answer: The wavelength of an electron moving 5.31 x 106 m/sec is 1.37 x 10-10 m or 1.37 Å.

### What is the formula of de Broglie wavelength?

Sample Problem: de Broglie Wave Equation Apply the de Broglie wave equation λ=hmv λ = h m v to solve for the wavelength of the moving electron.

### What is the ratio of de Broglie wavelength of proton and alpha particle?

Ratio of De-Broglie wavelengths of a proton and an alpha particle of the same energy is : 1 : 4.

Which has a greater de Broglie wavelength a proton or an electron moving with the same velocity?

Answer: The de Broglie wavelength of a particle is inversely proportional to its momentum p = m v; since a proton is about 1800 times more massive than an electron, its momentum at the same speed is 1800 times that of an electron, and therefore its wavelength 1800 times smaller. The electron has the longer wavelength.

#### What is de Broglie wavelength for an electron moving with velocity of light?

Calculate de Broglie wavelength of an electron travelling at 1 % of the speed of light. Wavelength of electron (λ)=hmυ=(6.626×10-34kgm2s-1)(9.1×10-31kg)×(3×106ms-1)=2.43×10-10m.

#### What is the de Broglie wavelength for the electron when it is in the N 4 level?

four times
Therefore, the de-Broglie wavelength associated with the electron in the n=4 level is four times the de-Broglie wavelength of the electron in the ground state. So, the correct answer is “Option B”.

What is Toppr de Broglie wavelength?

Experiments have proved that sometimes light behaves like a wave, while in others, it behaves like particles. This formula relates the wavelength to the momentum of a wave or particle. …

## What do you mean by de Broglie wavelength?

De Broglie wavelength is the wavelength associated with a matter wave. Both light and matter behave like a wave on a large scale and like a particle on a small scale. To calculate the matter wave, we use the formula de broglie wavelength = planck’s constant / momentum.

## How do you find the wavelength of an alpha particle?

How do you find the de Broglie wavelength of a photon?

The de Broglie wavelength of the photon can be computed using the formula: λ = h p = 6.62607 × 10 − 34 J s 1.50 × 10 − 27 k g m / s = 4.42 × 10 − 7 m

### What are de Broglie waves?

De-Broglie waves explain about the nature of the wave related to the particle. Einstein explained the momentum (p) of a photon with the given formula c = speed of light. h= Planck’s constant ( 6.62607015×10−34 Js) De Broglie Wavelength Formula is used to calculate the wavelength and momentum in any given problems based on this concept.

### What is the relationship between de Broglie wavelength and kinetic energy?

The relation between de-Broglie wavelength and the kinetic energy of an object of mass m moving with velocity v is given as: λ = h 2 m K When a charged particle having a charge q is accelerated through an external potential difference V, de-Broglie wavelength, λ = h v q V

What is the de Broglie equation?

This De Broglie equation is based on the fact that every object has a wavelength associated to it (or simply every particle has some wave character). This equation simply relates the wave character and the particle character of an object.
