E = h*(c/lambda)
E = 6.626*10^-34*3*10^8/(709.6*10^-9)
E = 2.8*10^-19 J/mol or 2.8*10^-22 Kj/mol
frequency = (C/lambda) = 4.2*10^-14 sec^-1
Red color appears
..................................................................................................
frequency = 5.982*10^14
E = h*f = 6.626*10^-34*5.982*10^14
E = 4.0*10^-19 J/mol or 4.0*10^-22Kj/mol
lambda = c/f = 3*10^8/5.982*10^14 = 5.01*10^-7 m or 501 nm
Blue green color appears
...................................................................................................................
E = 6.626*10^-34*3*10^8/(589.7*10^-9)
E = 3.37*-19 J/mol or 3.37*10^-22 Kj/mol
frequency = 5.08*10^14 sec^-1
.......................................................................................................
E = 258.8*10^3 J/mol
258.8*10^3 = 6.626*10^-34*f
f = 258.8*10^3 / 6.626*10^-34
f = 3.905*10^38 sec^-1
lambda = c/f = 3*10^8/3.905*10^38 = 7.68*10^-29 m = 7.68*10^-20 nm
