Question

Find the speed of the following objects given their de Broglie wavelength:

a. An electron with a wavelength of 0.2 nm

b. A proton with a wavelength of 0.2 nm

c. A 200 g baseball with a wavelength of 0.2 nm (in m/s and mi/hr)

d. Explain the differences.

Answer #1

An electron has a de Broglie wavelength of 215 nm, what is the
speed of the electron?

1) How will the wavelength of de Broglie electron change if you
increase it
speed 3 times?
2) How much is the wavelength of de Broglie proton different from
the wavelength
where is the Broglie electron if they move at the same speed?
3) Will the wavelength of the particle change if it enters the
potential field?

If the De Broglie wavelength of an electron is equal to 450
nm calculate the velocity of the electron. Assume that the
electron's speed is non-relativistic.
Tries 0/10
If the kinetic energy of an electron is 170 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.

Find the de Broglie wavelength of an electron with a speed of
0.95c. Take relativistic effects into account.

A. The mass of an electron is 9.11×10−31 kg. If the de Broglie
wavelength for an electron in a hydrogen atom is 3.31×10−10 m, how
fast is the electron moving relative to the speed of light? The
speed of light is 3.00×108 m/s. Calculate your answer as a
percentage.The solution was .732% B. The mass of a golf ball is
45.9 g . If it leaves the tee with a speed of 70.0 m/s , what is
its corresponding wavelength?...
