Wavelength x frequency = speed (of the wave), therefore, the frequency is the speed divided by the wavelength. If you are talking about an electromagnetic wave in a vacuum, its speed is approximately 300,000,000 m/s. Also, don't forget to convert the nanometers to meters before doing the division.
Indigo has a wavelength range of approximately 450-420 nanometers, which corresponds to the blue-violet part of the visible spectrum.
Purple is a mixture of the colors red and blue.
The wavelength is 671 nm.
Frequency is equal to constant divided by wavelength. 3.00x108 / 780nm equals approximately 4397435897.4359 hertz.
The frequency of a photon with a wavelength of 781 nm is approximately 384 THz (terahertz).

The frequency of light with a wavelength of 15 nm is approximately 2 x 10^16 Hz. The energy of light with this wavelength is about 80.6 electronvolts.
, there is a table below with the wavelength of each color. Color Wavelength in nm Violet 380 - 480 Indigo 420 - 450 Blue 450 - 495 Green 495 - 570 Yellow 570 - 590 Orange 590 - 620 Red 620 - 750
Using Wien's displacement law, we can relate the peak wavelength to the temperature of the star. The ratio of their temperatures is approximately 700 nm / 450 nm = 1.56.
The frequency of light with a wavelength of 700 nm can be calculated using the equation: frequency = speed of light / wavelength. The speed of light is approximately 3.00 x 10^8 m/s. Converting the wavelength to meters (700 nm = 700 x 10^-9 m), you can calculate the frequency.
The wavelength of the color violet is 450-400 nm, which can also be said as 450 to 400 nanometers.
Just divide the speed of light (in meters/second) by the frequency (in hertz) - that will give you the wavelength (in meters). You can then convert that to nm.
