i believe it is 400-700 nanometres
Red is the longest wavelength of visible light
Different.
The wave length of visible light ranges from 400 nm to 700 nm
Infrared light has longer wavelengths than visible light. Visible light ranges from about 400-700 nanometers in wavelength, while infrared light ranges from about 700 nanometers to 1 millimeter. This difference in wavelength determines how these types of light interact with matter and are perceived by our eyes.
The wavelength of Magnesium on the visible light spectrum ranges from approximately 380 to 580 nanometers, which corresponds to blue to green light.
Visible light ranges from red at about 750 nm to violet at around 400 nm.
The visible color of electromagnetic radiation with the shortest wavelength is violet. The wavelength of violet light ranges from approximately 380 to 450 nanometers.
The light spectrum is the range of electromagnetic radiation that is visible to the human eye. It consists of different wavelengths of light, each corresponding to a different color. The visible light spectrum ranges from violet (shortest wavelength) to red (longest wavelength).
Visible 'light' ranges from roughly 380 to 750 nanometers (billionths of a meter). It can vary somewhat for different individuals' eyes. If electromagnetic radiation has a wavelength longer than about 750nm or shorter than about 380nm, you may still call it 'light' if you want, but the human eye doesn't respond to it.
Red is the longest wavelength of visible light
The light that is visible to the human eye is called visible light. This portion of the electromagnetic spectrum ranges from violet to red, with each color corresponding to a different wavelength.
The longest wavelength / lowest frequency visible light is the red end of the spectrum. The shortest wavelength / highest frequency visible light is the violet end of the spectrum.
