Higher Physics - Unit 3 - Photoelectric Effect and Photons

I created my own revision notes for all units of the Higher Physics course.

These are revision notes for part of the 3rd unit (Radiation and Matter), section 3 (Optoelectronics and Semi-conductors). I've uploaded all the subsections of this section in different files as they are otherwise too large.

Photoelectric Effect and Photons covers:
• Meaning of the photoelectric effect
• Experiment to show the photoelectric effect
• Conditions for photoelectric effect to work
• What the work function is
• Further information on the work function
• Light is a photon
• What a photon is
• Properties of a photon
• Photon equations
