Solution : Here, `V=100` Volts. The de- Broglie wavelength `lambda ” is ” lambda =(1.227)/(sqrt(V))nm`. <br> `=(1.227)/(sqrt(100))=(1.227)/(10) =0.1227=0.123 nm`.
What is the de-Broglie wavelength of an electron accelerated from rest by a potential of 200v?
de-Broglie wavelength for an electron is given by lambda=h/√2meV. So, if you plugin the values of h(Planck’s constant),m(mass of electron),e(elementary charge of electron), in the above equation you get a value, lambda=12.27A°/√V. So, according to your problem, the answer is 1.227A°, where 1A°=10^(-10) m.

What is the de Broglie wavelength formula?
How do you calculate the de Broglie wavelength?
To determine the de Broglie wavelength of a particle given its mass and velocity, you need to:
- Multiply the velocity by mass. Their product is the particle’s momentum.
- Divide Planck’s constant by the momentum found in Step 1.
- The result you’ve got is exactly the de Broglie wavelength of your particle. Congrats!
