what is the frequency of red light wavelength?
315845
Red light has a wavelength of ~700 nm, and a frequency of ~4.3*1014 Hz. Visible light makes up just a small part of the full electromagnetic spectrum.

Light is measured by its wavelength (in nanometers) or frequency (in Hertz). One wavelength. equals the distance between two successive wave crests or troughs. Frequency (Hertz) equals the number of waves that passes a given point per second.
97361
IR frequencies range from about 300 gigahertz (GHz) up to about 400 terahertz (THz), and wavelengths are estimated to range between 1,000 micrometers (µm) and 760 nanometers (2.9921 inches), although these values are not definitive, according to NASA.

frequency x wavelength=wave speed. The frequency is inversely proportional to wavelength.

Visible light falls in the range of the EM spectrum between infrared (IR) and ultraviolet (UV). It has frequencies of about 4 × 1014 to 8 × 1014 cycles per second, or hertz (Hz) and wavelengths of about 740 nanometers (nm) or 2.9 × 10−5 inches, to 380 nm (1.5 × 10−5 inches).

They are all related by one important equation: Any electromagnetic wave's frequency multiplied by its wavelength equals the speed of light. FREQUENCY OF OSCILLATION x WAVELENGTH = SPEED OF LIGHT.

Red light is visible and is most effective for use on the surface of the skin. Red light occupies the “long end” of the visible spectrum with wavelengths of 630nm-700nm. Infrared light is invisible and is effective for use on the surface of the skin as well as penetration of about 1.5 inches into the body.

Far-red light is a range of light at the extreme red end of the visible spectrum, just before infra-red light. Usually regarded as the region between 700 and 780 nm wavelength, it is dimly visible to human eyes.

What do wavelength and frequency measure? ... Wavelength measures the distance between two peaks in a wave while frequency measures the number of times a wave repeats itself per unit time. These two properties are related by the speed of light equation which says that c = λν. 2.

The speed at which light travels through air is about 300 million meters per second. What is the relationship between color, wavelength, and frequency? The warmer the color, the longer the wavelength, and smaller the frequency. The cooler the color, the shorter the wavelength, and larger the frequency.
1149125
Light at the lower end of the visible spectrum, having a longer wavelength, about 740 nm, is seen as red; light in the middle of the spectrum is seen as green; and light at the upper end of the spectrum, with a wavelength of about 380 nm, is seen as violet.

To find wavelength ( λ ), the equation is manipulated so that λ=cν . What is the wavelength of a electromagnetic wave that has a frequency of 4.95×1014 Hz ? Once you have frequency, you can use the first equation c=λ⋅ν to find the wavelength.
366135
The wavelength and frequency of light are closely related. The higher the frequency, the shorter the wavelength. Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on the wavelength.
324428
Radio waves, microwaves and infrared have lower frequency than visible light. Shorter wavelength: Ultraviolet, x-rays and gamma rays have a shorter wavelength than visible light.
88994
Electromagnetic radiation in this range of wavelengths is called visible light or simply light. A typical human eye will respond to wavelengths from about 380 to 740 nanometers. In terms of frequency, this corresponds to a band in the vicinity of 405–790 THz.

Electromagnetic radiation with a wavelength of 745 nm appears as red light to the human eye. The frequency of this light is _ s-1.
