If the Electromagnetic Spectrum ranges from Wavelengths of around 10^-4 to 10^14 nanometers & Visible Light Spectrum ranges from Wavelengths of around 400 to 800 nanometers, then the Visible Light Spectrum percentage of the whole Electromagnetic Spectrum is:

= 400 x 100 / 10^18

= 4 x 10^-14

= 0.00000000000004%.

That means what the Human Eye sees is only 0.00000000000004% of what is “really” out there.

Humans call that percentage as “Reality” & kill each other over control of it.

[NOTE 1:

The Percentage of Visible Light Range (400 – 750 nm) in the whole of the “Useful” Electromagnetic Spectrum Range (1 – 10^7 nm) published in Public Domain is given as:

= 350 x 100 / 10^7

= 35 x 10^-4

= 0.0035%.]

[NOTE 2:

1 nanometer (nm) = 10^-9 meters (m)]

[NOTE 3:

Velocity of Light can be roughly calculated as (Visible Range Average):

= 500 nanometers x 600 terrahertz
= 3 x 10^8 meters/second
= 300,000 kilometres/second]
