IB DP Physics: HL复习笔记12.1.8 The Wave Function
The Wave Function Bohr showed that the angular momentum of an electron orbiting a hydrogen atom was quantised He also showed that the allowed electron energies were also quantised Unfortunately, th...
IB DP Physics: HL复习笔记12.1.7 Quantization of Angular Momentum
Quantization of Angular Momentum Angular momentum is a property of any spinning or rotating body, very similar to linear momentum In linear motion, momentum is the product of mass and velocity In r...
IB DP Physics: HL复习笔记12.1.6 Pair Production & Annihilation
Pair Production & Annihilation Annihilation When a particle meets its antiparticle pair, the two will annihilate Annihilation is: When a particle meets its equivalent anti–particle they both ar...
IB DP Physics: HL复习笔记12.1.5 Matter Waves
Matter Waves De Broglie proposed that electrons travel through space as a wave This would explain why they can exhibit behaviour such as diffraction He therefore suggested that electrons must also ...
IB DP Physics: HL复习笔记12.1.4 Solving Photoelectric Problems
Solving Photoelectric Problems Since energy is always conserved, the energy of an incident photon is equal to: The work function + the maximum kinetic energy of the photoelectron The energy within ...
IB DP Physics: HL复习笔记12.1.3 Observing the Photoelectric Effect
Observing the Photoelectric Effect The photoelectric effect can be observed on a gold leaf electroscope A plate of metal, usually zinc, is attached to a gold leaf, which initially has a negative ch...
IB DP Physics: HL复习笔记12.1.2 The Photoelectric Effect
The Photoelectric Effect The photoelectric effect is the phenomena in which electrons are emitted from the surface of a metal upon the absorption of electromagnetic radiation Electrons removed from...

IB DP Physics: HL复习笔记11.3.7 Discharge Calculations
Capacitor Discharge Equation The time constant is used in the exponential decay equations for the current, charge or potential difference (p.d) for a capacitor discharging through a resistor These ...
IB DP Physics: HL复习笔记11.3.6 Capacitor Charge & Discharge
Exponential Discharge of a Capacitor Charging Capacitors are charged by a power supply (eg. a battery) When charging, the electrons are pulled from the plate connected to the positive terminal of t...
IB DP Physics: HL复习笔记11.3.5 Energy Stored in a Capacitor
Energy Stored in a Capacitor When charging a capacitor, the power supply pushes electrons from the positive to the negative plate It therefore does work on the electrons and electrical energy becom...
IB DP Physics: HL复习笔记11.3.4 The Time Constant
The Time Constant The time constant of a capacitor discharging through a resistor is a measure of how long it takes for the capacitor to discharge The definition of the time constant is: The time t...
