a potential difference of 250 V?

Answer #1

de Broglie wavelength = 7.761 x 10-12 m

Speed = 9.377 x 107 m/s

1. a) What is the de Broglie wavelength of an electron that is
accelerated through an electrical potential difference of 20 volts?
b) What is the de Broglie wavelength of a proton that is
accelerated through an electrical potential difference of 20
volts?

PART A: What is the de Broglie wavelength of an electron
accelerated through 750 V ? Express your answer in nanometers.
PART B: What is the de Broglie wavelength of a proton
accelerated through the same potential difference?
Express your answer in nanometers.

An electron and a proton are accelerated through a
potential difference of 1.2kV. What is the ratio of the electrons
de Broglie wavelength to the protons de Broglie wavelength?

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?

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

If the de Broglie wavelength of a proton is 70.0 fm,
(a) what is the speed of the proton and
(b) through what electric potential would the
proton have to be accelerated to acquire this speed?

An electron is accelerated through a potential difference of 100
V.
a. What is the velocity of the electron?
v = _______ x10 6 m/s
b. What is the momentum of the electron?
p = _______ x10 -24 kg m/s
c. What is the de Broglie wavelength of the electron?
λ = _______ nm

What is the de Broglie wavelength of the wave associated with an
electron that has been accelerated from rest through a potential of
50.0 V? Compare your answer to the typical distance between atoms
in a solid crystal, about10−10 ?. Would you expect diffraction to
occur as these electrons pass between such atoms?

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

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.
