Compton Wavelength and Photon Behavior

The video explains the Compton Effect, detailing how photons interact with electrons, leading to changes in wavelength. It covers the calculation of the Compton wavelength for electrons and protons, and how scattering angles affect photon energy and wavelength. The video also compares the Compton wavelengths of electrons and protons, highlighting the relationship between mass and rest energy.

What happens to a photon when it is absorbed by an electron and the electron is knocked out of the atom?

• The photon increases in energy.

• The photon changes color.

• The photon disappears.

• The photon is scattered.

In the Compton Effect, what is the relationship between the original and scattered photon wavelengths?

• The scattered wavelength is equal to the original wavelength.

• The scattered wavelength is longer than the original wavelength.

• The scattered wavelength is always shorter.

• The scattered wavelength is unrelated to the original wavelength.

What is the Compton wavelength of an electron?

• 2.4 nanometers

• 0.0024 nanometers

• 0.024 nanometers

Which factor does NOT affect the change in wavelength of a scattered photon?

• Scattering angle

• Mass of the particle

• Original wavelength

• Color of the photon

How does the wavelength of a photon change when scattered at a 90-degree angle?

• It decreases by one Compton wavelength.

• It remains the same.

• It increases by one Compton wavelength.

• It doubles.

What is the maximum change in wavelength for a photon scattered at 180 degrees?

• No change

• Three Compton wavelengths

• Two Compton wavelengths

• One Compton wavelength

What is the effect on photon energy when its wavelength increases?

• Energy becomes zero.

• Energy remains constant.

• Energy decreases.

• Energy increases.

How does the Compton wavelength of a proton compare to that of an electron?

• It is unrelated to that of an electron.

• It is smaller than that of an electron.

• It is the same as that of an electron.

• It is larger than that of an electron.

What does a smaller Compton wavelength indicate about a particle's rest energy?

• The rest energy is lower.

• The rest energy is zero.

• The rest energy is higher.

• The rest energy is unchanged.
