Frequencies and Wavelengths of Colors in the Visible Light Spectrum

Postby Samantha Pedersen 2K » Mon Oct 05, 2020 7:17 pm

What are the frequencies and wavelengths of the visible light spectrum? I did some searching and found that the wavelengths are between 380 nm and 740 nm while the frequencies are 4.0 x 10^14 Hz and 7.90 x 10^14 Hz, but I wanted to make sure those are correct.

Also, what are the frequencies of each color in the visible light spectrum?

I believe your range is pretty accurate with violet being around 380 nm and red being around 710 nm. Because visible light is a spectrum of color, I doubt you will have to know the specific frequency of ROYGBV since each color covers a range of wavelengths. :)

Hi! I believe your wavelengths are correct, but I'm not sure of the frequency but I think it's pretty close to what you have down (some sources say a little more that 4.0x 10^14 Hz, like 4.8x 10^14 Hz or 4.6x 10^14 Hz). I found a diagram that might show the frequencies of each color but I'm not 100% sure if the source is reliable. Hope this kinda helps!

I also believe that your range is pretty on par with what I found as well as it does tend to range from ~400 nm to ~700 nm. For frequencies, I found that violet light has a frequency around 7.5x10^14 Hz and red has a frequency around 4.3x10^14 Hz. I doubt you will have to memorize specific frequencies as well but it may help when doing quantum mechanics problems.

Lavelle did also say that making it more basic, from 400 nm to 700 nm, would make the range more simple and easier to comprehend
