Concept explainers
To Calculate: The de Broglie wavelength of electron.
Answer to Problem 31SSC
Explanation of Solution
Given data:
Potential difference is
Formula used:
de Broglie wavelength
Kinetic energy in terms of potential difference is
Therefore, de Broglie wavelength in terms of potential difference is
Where,
v = velocity of electron
Calculation:
Planck’s constant,
Mass of electron,
Charge of electron,
Given Potential difference,
Substitute the values and solve:
Conclusion:
Therefore, de Broglie wavelength is
