Study Notes
Types of Electromagnetic Radiation (EMR)
- EMR includes gamma rays, X-rays, ultraviolet (UV) radiation, visible light, infrared (IR) radiation, microwaves, and radio waves
Electromagnetic Waves in Classical Physics
- Electromagnetic waves are oscillations of electric and magnetic fields that propagate through space
- According to classical physics, electromagnetic waves are created by the acceleration of charged particles
Travel of Electromagnetic Waves in a Vacuum
- Electromagnetic waves can travel through a vacuum because they do not require a medium to propagate
- In a vacuum, electromagnetic waves travel at the speed of light (c = 299,792,458 m/s)
Oscillations of Electric and Magnetic Fields
- In homogeneous, isotropic media, electric and magnetic fields oscillate perpendicularly to each other and the direction of propagation
- The oscillations of electric and magnetic fields are in phase with each other
Characterization of Electromagnetic Waves
- The position of an electromagnetic wave within the electromagnetic spectrum can be characterized by its frequency (ν), wavelength (λ), and energy (E)
- Electromagnetic waves can be characterized by their frequency range, energy, and application (e.g., gamma rays for medical treatments, radio waves for communication)
