# Calculate the wavelength of an electron traveling at 1.12*10^5m/s

• plstevens
In summary, the formula for calculating the wavelength of an electron is λ = h/mv, where λ is the wavelength, h is Planck's constant, m is the mass of the electron, and v is the velocity of the electron. This formula can be used for all velocities of electrons, but as the velocity increases, the wavelength decreases. Planck's constant, which is used in the formula, is 6.626 x 10^-34 m^2 kg/s and is a fundamental constant in quantum mechanics. It is not a constant value, as it depends on the velocity of the electron, which can vary depending on the conditions of the experiment.

lamda=_______m

uh, i don't understand it or i would but thanks for all your help! But if someone else could please help me with this problem that would be greatly appreciated

i just got it, it's 0.649*10^-8.

If you want help from anyone in here, you have to show an attempt.

meters is the unit, by the way

well thanks anyway but i figured it out.

## 1. What is the formula for calculating the wavelength of an electron?

The formula for calculating the wavelength of an electron is: λ = h/mv, where λ is the wavelength, h is Planck's constant (6.626 x 10^-34 m^2 kg/s), m is the mass of the electron (9.11 x 10^-31 kg), and v is the velocity of the electron.

## 2. How do I convert the given velocity of an electron from m/s to m/s?

To convert the given velocity of the electron from m/s to m/s, you can simply multiply the given value by 1. This will not change the value, but it will make the unit consistent. In this case, the given velocity of 1.12 x 10^5 m/s remains the same when converted to m/s.

## 3. What is the value of Planck's constant used in the formula for calculating the wavelength of an electron?

The value of Planck's constant used in the formula for calculating the wavelength of an electron is 6.626 x 10^-34 m^2 kg/s. This is a fundamental constant in quantum mechanics and is used to relate the energy of a photon to its frequency.

## 4. Can the formula for calculating the wavelength of an electron be used for all velocities of electrons?

Yes, the formula for calculating the wavelength of an electron can be used for all velocities of electrons. However, it is important to note that as the velocity increases, the wavelength of the electron decreases.

## 5. Is the wavelength of an electron a constant value?

No, the wavelength of an electron is not a constant value. It depends on the velocity of the electron, which can vary depending on the conditions of the experiment. Therefore, the wavelength of an electron can vary as well.
