Electromagnetic Oscillations & Alternating Current
-
This chapter explores electromagnetic oscillations, focusing on RLC (Resistance-Inductance-Capacitance) circuits and their behavior under alternating current. It also covers the operation and applications of transformers, which are essential for the efficient transmission of electrical energy. Topics include the analysis of oscillating circuits, resonance, and the basic principles of transformers, including the turns ratio and impedance matching.
Chapter 32
Maxwell’s Equations & Magnetism of Matter
-
This chapter begins with a review of Maxwell's equations, which are fundamental to understanding electromagnetic phenomena. It then delves into magnetism in matter, focusing on the concepts of spin and magnetic moment. The chapter also explains the differences between diamagnetic, paramagnetic, and ferromagnetic materials, describing how each type of material responds to an applied magnetic field. Topics include the underlying microscopic mechanisms of these magnetic properties and their implications in various technological applications.
Chapter 33
Electromagnetic Waves
-
This chapter explores the fundamentals of electromagnetic waves, covering the EM spectrum, energy transport via the Poynting vector, and radiation pressure. It also discusses polarization, and the principles of reflection, refraction, and total internal reflection. These concepts are crucial for understanding how EM waves interact with different media and their practical applications.
Chapter 34
Geometrical Optics
-
​​This chapter on geometrical optics covers the principles of light reflection and refraction using plane and spherical mirrors, as well as spherical refractive surfaces. It also explores the functionality of thin lenses and their applications in various optical instruments.
Chapter 35
Interferences
-
​​This chapter on interference explores the wave nature of light, demonstrated through Young's interference experiment and the intensity patterns in double-slit setups. It also covers interference phenomena in thin films and the principles behind Michelson's interferometer.
