I'm not sure of the engish term but I think it's retinal persistence. the problem is that the eye has not the same refresh rate on all it's surface. I got sensitive eyes and that's why I'm very picky about refresh rates. i need 80Hz to feel comfortable when looking at the screen. any lower i can see it flash.
#E=hf#. What color our eyes register is determined by the frequency of the light wave hitting our eyes, i.e. how fast the wave is hitting our eyes. Frequency #f# and wavelength #lambda# are inversely proportional, the relationship between them is #v=flambda#, where #v# is the speed of the wave. For light waves in vacuum, #v=c#, the speed of light, #3*10^8m/s#. So the frequency (measured in Hertz) times the wavelength (measured in meters) will always equal #3*10^8#.
