The camera app? You need to be more specific about what wave properties you are trying to detect.

Range of Wavelengths (nm)	and Range of Frequencies (Hz) please

You can convert RGB value of pixel to wavelength and/or frequency.

Find HSB (aka "HSV") color space conversion routine. Hue is almost exactly matching 700 nm ... 400 nm.

(math formulas are in the middle of the article)

Sounds like you need a program that will do a Fourier transform (and histogram) of the image. I am not aware of anything that will run on a phone. You might have to download the image and use a PC-based tool.
