Study Notes
Light and Electromagnetic Radiation
- Visible light is electromagnetic radiation that can be perceived by the human eye, with wavelengths between 400-700 nanometers (nm) and frequencies of 750-420 terahertz.
- Visible light falls between infrared (with longer wavelengths) and ultraviolet (with shorter wavelengths) on the electromagnetic spectrum.
- The term "light" can refer to electromagnetic radiation of any wavelength, including gamma rays, X-rays, microwaves, and radio waves.
- Primary properties of light include intensity, propagation direction, frequency or wavelength spectrum, and polarization.
Characteristics of Light
- Light in vacuum travels at a speed of 299792458 m/s, a fundamental constant of nature.
- Light consists of massless elementary particles called photons, which represent the quanta of the electromagnetic field.
- Light can be analyzed as both waves and particles.
Study of Light
- The study of light is known as optics.
