Frequency refers to the number of cycles per second of a wave, such as the oscillation of an electromagnetic field in a laser.
In this article, we’ll explore the fascinating relationship between wavelength and frequency, with a specific focus on the applications of this concept in the context of wavelengths of light and lasers.
Which color of light has the shortest wavelength? Violet light has wavelengths ranging from approximately 380 to 450 nanometers. As you move from violet to other colors in the visible spectrum, such as indigo, blue, green, yellow, orange, and finally red, the wavelengths of these colors progressively increase.
Laser linewidth is a term that is used to describe the spectral width of a laser beam. It is a measure of the range of wavelengths that are emitted by the laser, and is typically expressed in units of nanometers (nm).
