What is the photoelectric effect? In this video, we explain the photoelectric effect in simple words — from how photons knock electrons off metal surfaces to threshold frequency, work function, and Planck's constant. Learn why Einstein won the Nobel Prize for this discovery and how it powers solar panels today.
Whether you're a physics student, preparing for exams, or curious about how light interacts with matter, this beginner-friendly animated explainer makes one of quantum physics' foundational concepts easy to understand.
