CHAPTER6

The Quantum Theory of Light

In This Chapter

  • Another unresolved mystery of classical physics
  • Albert Einstein’s “heuristic principle”
  • The photon and its detection
  • Light’s dual personality

In this chapter we’ll explore a second important case of quantization, this time in the form of light quanta, and learn how it provides an elegant interpretation of Max Planck’s blackbody radiation solution.
