let say this is my code f=imread('/tmp/marbles.jpg'); f=uint8(f); %need to convert back to uint8 to show picture

%Split into RGB Channels f_red = f(:,:,1); f_green = f(:,:,2); f_blue = f(:,:,3); the values of red , green and bleu are sorted but at a particular point they all interset e.g (2 6). what is the wavelenth at position (2,6). please can someone help me to generate the code if possible?
