This course has images and animations to explain the photoelectric effect, which can only be explained by particle nature of light. This keeps the debate going , on light being both a particle and a wave at the same time, depending on the situation.
Following topics are covered:
1. Photoelectric effect.:- threshold wavelength.
2. Practical: Experiment to study photoelectric effect. Stopping potential.
3. Why wave theory is not able to explain photoelectric effect.
4. Electrons too behave both as particle and wave.
Solved problems and test questions are given at the end.
