All Flashcards
Label the parts of the Compton Effect diagram.
1: Incident Photon, 2: Electron, 3: Scattered Photon
What is the difference between interference and diffraction?
Interference: Superposition of waves | Diffraction: Bending of waves around obstacles
Compare wave and particle properties.
Waves: Exhibit interference and diffraction. Described by wavelength and frequency. | Particles: Exhibit localized behavior and momentum. Described by mass and velocity.
What is the effect of increasing a particle's velocity on its de Broglie wavelength?
The de Broglie wavelength decreases.
What is the effect of increasing a photon's energy on its momentum?
The photon's momentum increases.
What happens when a photon scatters off an electron in the Compton Effect?
The photon loses energy (increases in wavelength) and changes direction, while the electron gains kinetic energy.
What happens to the mass of an object as its velocity increases, according to relativistic mass-energy equivalence?
Its mass increases.
What is the effect of passing waves through a narrow opening?
The waves diffract, spreading out as they pass through the opening.
