Visible light consists of electromagnetic waves with wavelengths (in air) in the range 400 - 700 nm. What are the frequencies of visible light?
Since this is not my area of expertise, I searched Google under the key words "visible light frequency" to get these possible sources:

http://en.wikipedia.org/wiki/Visible_spectrum

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
I hope this helps.
use
velocity=(wavelength)(frequency)
solve for frequency
where velocity is equal to speed of light.
To find the frequencies of visible light, we can use the formula:
c = λ * f
Where:
c is the speed of light (approximately 3.00 × 10^8 meters per second),
λ is the wavelength of light, and
f is the frequency of light.
Since we are given the wavelength range for visible light as 400 - 700 nm (nanometers), we can convert this to meters by dividing the values by 1,000,000 (since there are 1,000,000 nanometers in a meter).
So, the wavelength range becomes 4.00 × 10^-7 meters to 7.00 × 10^-7 meters.
Using the formula, we can calculate the frequencies of visible light:
For the lower bound:
c = λ * f
3.00 × 10^8 = 4.00 × 10^-7 * f
f = 3.00 × 10^8 / 4.00 × 10^-7
f ≈ 7.50 × 10^14 Hz
For the upper bound:
c = λ * f
3.00 × 10^8 = 7.00 × 10^-7 * f
f = 3.00 × 10^8 / 7.00 × 10^-7
f ≈ 4.29 × 10^14 Hz
Therefore, the frequencies of visible light range from approximately 4.29 × 10^14 Hz to 7.50 × 10^14 Hz.
