How do you calculate the de Broglie wavelength?
- Determine the momentum (p) of the particle. 2. Use the formula , where h is Planck's constant.
What are the steps to calculate the de Broglie wavelength of an electron accelerated through a potential difference?
- Find the kinetic energy (K) using . 2. Calculate the momentum using . 3. Calculate the de Broglie wavelength using .
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.
Label the parts of the Compton Effect diagram.
