What is (a) the wavelength of a 5.10-eV photon
and (b) the de Broglie wavelength of a 5.10-eV
electron?

What is (a) the wavelength of a 4.90-eV photon
and (b) the de Broglie wavelength of a 4.90-eV
electron?

A photon of wavelength 5.58 pm scatters at an angle of 122° from
an initially stationary, unbound electron. What is the de Broglie
wavelength(in pm) of the electron after the photon has been
scattered??
Notice: Answer is not (9.29, 2.12, 2.06, nor 4.11)pm
Explanation:
The de Broglie wavelength of a massive particle is related to
its momentum in the same way that a photon's momentum is related to
its wavelength.
The well-known Compton scattering relationship gives the final
wavelength of...

What is the kinetic energy in eV of an electron whose de Broglie
wavelength is 18 % of the wavelength of a photon having the energy
equal to electrons kinetic energy?
Answer in eV

Calculate the de Broglie wavelength of a ? - particle ejected
from the nucleus of a radioactive element with a kinetic energy of
7.5 eV. What is the frequency of a photon with the same
wavelength?

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.

An electron in a one-dimensional “box” has the
wave-function
(i) What value of the de Broglie wavelength does the electron
have ? (ii) What value of momentum does it have ? (iii) What value
of kinetic energy does it have ?

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 258 nm , what is
the kinetic energy of this electron?

Calculate the linear momentum, and the de Broglie wavelength
of:
a) a 0.75 kg bullet that is fired at a speed of 100 m /
s,
b) a non-relativistic electron with a kinetic energy of 2.0
eV, and
c) a relativistic electron with a kinetic energy of 208
keV.
!!!! # !! Remember that for relativistic particles: ? = ? ? +
? "? and ? = ?? = ? + ?" ?, the mass
of the electron is 9.11...
