The Photoelectric Effect - A Level Physics

This resource is a complete lesson that covers The Photoelectric Effect for the OCR A Level Physics A course. However, it is useful for other exam boards too.

This lesson teaches the following content:
-photoelectric effect, including a simple experiment to demonstrate this effect
-demonstration of the photoelectric effect using, e.g. gold-leaf electroscope and zinc plate
-a one-to-one interaction between a photon and a surface electron
-Einstein’s photoelectric equation hf = 𝜙 + KEmax
-work function; threshold frequency
-the idea that the maximum kinetic energy of the photoelectrons is independent of the intensity of the incident radiation
-the idea that rate of emission of photoelectrons above the threshold frequency is directly proportional to the intensity of the incident radiation.

This lesson includes:
-A full presentation including 3 example questions with worked solutions.
-A worksheet with model answers, perfect to set as homework.
-Clear visual aids and diagrams to simplify complex concepts.
-Editable PowerPoint and Word document for easy customisation.
