Using the formula:
c=λf
where c is the speed of light in m.s-1;
λ is the wavelength in metres;
f is the frequency in Hz
We know that the speed of light is 3.0 x 108m.s-1 and the frequency is 4.6 x 1014Hz.
Therefore:
λ=c/f
λ=(3.0 x 108)/(4.6 x 1014)
λ≈6.52 x 10-7m

Frequency = speed/wavelength = 3 x 108/1.87 x 10-14 = 1.6043 x 1022 Hz.Note:That's no light. That's well into the gamma rays.
The wavelength is 678,68 nm.
5.40 x 10^14 Hz
5.68 X 10^14? Then, speed of light = frequency * wavelength so, 2.998 X 10^8 m/s/5.68 X 10^14 s^1 = 5.278 X 10^-7 meters, or, 527.8 nanometers That would be green, I think.

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.

velocity = frequency x wavelength 3x10^8 = f x 4.90x10^-7 f = 6.12x10^14 Hz
Frequency=velocity of light/wavelength We know that the velocity of light is 3x10^8m/s From your wavelength, I am assuming that the number is in meters Thus the frequency =(3x10^8)/(6.14x10^-7) frequency = 4.8859x10^14 Hz
Wavelength = (speed)/(frequency) = 299,792,458/4 x 1015 = 7.4948 x 10-8 meter = 74.95 nm (rounded)
The wavelength of ultraviolet light is between 10 and 400 nanometers (nm).From the wavelength you can determine the frequency. If you divide the speed of light by the wavelength, you can calculate the frequency.The frequency range would be from 7.5 x 1014 Hz to 3 x 1016 Hz.
Infrared and Ultraviolet light fall just outside human vision. The frequency of infrared light is less than the frequency of visible red light. There are different definitions and classifications of infrared, but the frequency ranges from 3 x 10 11 Hz (300 Gigahertz or 1000 micrometer wavelength) to about 4.3 x 10 14 Hz (0.7 micrometer wavelength). Ultraviolet's frequency is greater than the frequency of Violet light. This can range from 7.5 x 10 14 Hz (400 nanometer wavelength) to 3.0 x 10 16 Hz (10 nanometer wavelength). See related links.
Since, frequency, f = c / λ Then, λ = 405 x 10-6 cm = 4.05 x 10-10 m Speed of light c = 299,792,458 m/s Therefore, frequency f = 299,792,458 m/s / 4.05 x 10-10 m = 740,228,291,358,024,691 Hz = 7.40 x 1017 Hertz.
