Dual Nature of Matter and Radiation Cheatsheet & Quiz

Photoelectric Effect: \( E = h \nu \), where \( E \) is photon energy, \( h \) Planck’s constant, \( \nu \) frequency.
Work Function: \( \phi = h \nu_0 \), minimum energy to eject an electron.
Einstein’s Photoelectric Equation: \( h \nu = \phi + \frac{1}{2} m v_{\text{max}}^2 \).
de Broglie Wavelength: \( \lambda = \frac{h}{p} = \frac{h}{m v} \), where \( p \) is momentum.
Photon Momentum: \( p = \frac{h}{\lambda} = \frac{E}{c} \).
Wave-Particle Duality: Matter exhibits both particle and wave-like properties.
Uncertainty Principle: \( \Delta x \cdot \Delta p \geq \frac{h}{4 \pi} \).
Planck’s Constant: \( h = 6.626 \times 10^{-34} \, \text{J·s} \).
Stopping Potential: \( e V_s = \frac{1}{2} m v_{\text{max}}^2 \).
Davisson-Germer Experiment: Confirms electron wave nature via diffraction.

Type	Concept	Formula/Description
Photoelectric	Photon Energy	\( E = h \nu \)
Work Function	Threshold Energy	\( \phi = h \nu_0 \)
Photoelectric Eq	Energy Conservation	\( h \nu = \phi + \frac{1}{2} m v_{\text{max}}^2 \)
de Broglie	Matter Wave	\( \lambda = \frac{h}{p} \)
Uncertainty	Heisenberg Principle	\( \Delta x \cdot \Delta p \geq \frac{h}{4 \pi} \)
Photon Momentum	Light Momentum	\( p = \frac{h}{\lambda} \)

Identify Context: Determine if the problem involves photons or matter waves.

Use Formulas: Apply Einstein’s photoelectric equation for light, de Broglie for matter.

Units: Ensure consistency in units, especially for energy (eV or J) and wavelength (m or nm).

Threshold Frequency: Always check for \( \nu_0 \) in photoelectric problems.

Verify: Cross-check calculations with physical principles like energy conservation.

Photoelectric Effect: Use \( h \nu = \phi + \frac{1}{2} m v_{\text{max}}^2 \) for electron emission problems.
de Broglie Wavelength: Apply \( \lambda = \frac{h}{p} \) for particles like electrons or protons.
Photon Energy: Calculate energy using \( E = h \nu \) or \( E = \frac{h c}{\lambda} \).
Uncertainty Principle: Use \( \Delta x \cdot \Delta p \geq \frac{h}{4 \pi} \) for position-momentum problems.
Stopping Potential: Relate to kinetic energy via \( e V_s = \frac{1}{2} m v_{\text{max}}^2 \).
