CHAPTER 2
Particle Properties of Waves 52
2.1 Electromagnetic Waves 53
Coupled electric and magnetic oscillations that move with the speed of
light and exhibit typical wave behavior
2.2 Blackbody Radiation 57
Only the quantum theory of light can explain its origin
2.3 Photoelectric Effect 62
The energies of electrons liberated by light depend on the frequency
of the light
2.4 What Is Light? 67
Both wave and particle
2.5 X-Rays 68
They consist of high-energy photons
2.6 X-Ray Diffraction 72
How x-ray wavelengths can be determined
2.7 Compton Effect 75
Further confirmation of the photon model
2.8 Pair Production 79
Energy into matter
2.9 Photons and Gravity 85
Although they lack rest mass, photons behave as though they have
gravitational massCHAPTER 3
Wave Properties of Particles 92
3.1 De Broglie Waves 93
A moving body behaves in certain ways as though it has a wave nature
3.2 Waves of What? 95
Waves of probability
3.3 Describing a Wave 96
A general formula for waves
3.4 Phase and Group Velocities 99
A group of waves need not have the same velocity as the waves
themselves
3.5 Particle Diffraction 104
An experiment that confirms the existence of de Broglie wavesiv Contents
