Morse code is a reliable system as the signal is made up of only three parts – a long ‘on’, the dash; a short ‘on’, the dot; and an ‘off’ signal. Do you know what SOS means in Morse code?

Differentiating wavelengths

Normal humans have three different types of cones with photo-pigments that sense three different portions of the spectrum. Each cone is tuned to perceive mostly either Long wavelengths (reddish), Middle wavelengths (greenish), or Short wavelengths (bluish), referred to as L-, M-, and S- cones.
