Chapter 9: The Lorentz Transformations
9.1 Introduction to the Lorentz Transformations The Lorentz transformations are a set of mathematical equations that describe the relationship between the space and time coordinates of events in different inertial frames of reference moving relative to one another. These transformations are essential for understanding the principles of special relativity, including time dilation and length contraction.…

Speed of Light
Introduction The speed of light, typically denoted by , is a fundamental constant of nature that represents the speed at which light travels in a vacuum. It is an important concept in many areas of physics, such as electromagnetism and relativity. Value and Units The speed of light in a vacuum is defined to be…

Visible Light
Introduction Visible light is the portion of the electromagnetic spectrum that is visible to the human eye. It occupies a very small portion of the electromagnetic spectrum, roughly between the wavelengths of 400 and 700 nanometers. Electromagnetic Spectrum and Visible Light The electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation. It…

Electromagnetic Waves
Introduction Electromagnetic waves are waves of electric and magnetic fields that propagate through space carrying electromagnetic energy. They are solutions to Maxwell’s equations and encompass a wide range of phenomena including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. Maxwell’s Equations Maxwell’s equations describe the behavior of both the electric and magnetic…
