1. (A) Find the de Broglie wavelength (in nm) associated with an electron that is moving with a velocity of 2310 km/s. The electron rest mass is 9.11 x 10-31 kg. Note, electrons having this speed would need to be treated as waves in atoms because the wavelength is on the order of the size of atoms. (B) A baseball weighs 220 g. Top speed for a professional pitcher is about 100 mph when he throws a fast ball. Find...

Find the de Broglie wavelength λ for an electron moving at a speed of 1.00×106m/s. (Note that this speed is low enough that the classical momentum formula p=mv is still valid.) Recall that the mass of an electron is me=9.11×10−31kg, and Planck's constant is h=6.626×10−34J⋅s.
What is the velocity of an electron that has a de Broglie wavelength of 274 pm? (1 pm = 10-12 m, mass of electron = 9.11 x 10-31 kg)
A) If the De Broglie wavelength of an electron is equal to 350 nm calculate the velocity of the electron. Assume that the electron's speed is non-relativistic. B) If the kinetic energy of an electron is 440 eV, calculate its De Broglie wavelength. For this non-relativistic electron you must first calculate its velocity from the general kinetic energy equation. Then you can find the De Broglie wavelength of the electron.

If the De Broglie wavelength of an electron is equal to 400 nm calculate the velocity of the electron. Assume that the electron's speed is non-relativistic. Answer: 1832.42 m/s If the kinetic energy of an electron is 400 eV, calculate its De Broglie wavelength. For this non-relativistic electron you must first calculate its velocity from the general kinetic energy equation. Then you can find the De Broglie wavelength of the electron. I cannot figure out the second part, please explain!
2. Estimate the de Broglie wavelength of an electron (me - 9.11 x 10- kg) as it orbits a hydrogen atom with a period of 0.166 fs. (1 fs = 1 x 10-'s). Take the Bohr radius to be 0.05 nm.
