Blue light has shorter wavelengths and higher energy than other colors. Some research shows a link between eye damage and short-wave blue light with wavelengths between 415 and 455 nanometers. Most of the light from the LEDs used in smartphones, TVs, and tablets has wavelengths between 400 and 490 nanometers.2 Eki 2020

From longest to shortest wavelength, they are: red, orange, yellow, green, blue, indigo, and violet . To be clear, color is the eye’s perception of different wavelengths of electromagnetic light.
Read moreCan frequency be GHz?
Gigahertz (GHz) is a frequency unit that measures the number of cycles per second . Hertz (Hz) refers to the number of cycles per second with periodic 1-second intervals. One megahertz (MHz) equals 1,000,000 Hz. One gigahertz is equal to 1,000 megahertz (MHz) or 1,000,000,000 Hz.
