What happens when light behaves like a particle?
In this lecture, we explore the Photoelectric Effect—the experiment that shook the foundations of classical physics and forced scientists to rethink the nature of light itself.

Classical wave theory completely failed to explain:

• Why increasing light intensity didn’t always eject electrons
• Why frequency mattered more than brightness
• Why electrons were emitted instantly

This mystery was finally solved when Einstein introduced the quantum idea of light, earning him the Nobel Prize and marking a turning point in modern physics.

✨ In this video, you’ll understand:

What the photoelectric effect actually is
Why classical physics failed?

Einstein’s revolutionary explanation

How this experiment proved the particle nature of light

Why it was a stepping stone to quantum mechanics



If you’re a Class 12 student, JEE/NEET/CSIR-NET aspirant, or simply curious about how quantum physics was born, this lecture is for you.
🔔 Stay tuned—this is a crucial chapter in our Quantum Mechanics series, where we uncover how nature truly works at the microscopic level.
