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...
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 ...
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 ...
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...
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...
上海阿德科特學校是英國阿德科特學校的第一家海外分校，于2018年9月正式開學。為讓更多的家長了解上海阿德科特，學?，F于8月11日舉辦校園開放日的活動，名額有限，趕緊來報名吧！ 招考信息 開設年級：高中 考試時...
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 ...
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...
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...
