Chapter 7: Quantum Physics
What you need to learn in this chapter
In this chapter, we will be learning about quantum physics. We will start by understanding the background of the quantum theory and what quantum energy means.
Next, we will explore the effects of photoelectric and learn about four features that cannot be explained using wave theory.
Finally, we will study Einstein's photoelectric theory and understand the minimum work function needed for a metal to emit electrons.
We will also learn about threshold frequency and work function. By the end of this chapter, we will have a solid understanding of these concepts in quantum physics.
