Visible trades are material or physical things that are imported or exported by

LIGHT

 * Refraction is the bending of light as it goes from one medium to another.
   
 * Laws of Refraction: (1) Incident ray, refracted ray & normal are on the same
   plane. (2) Sine I/Sine R is constant.
 * Refractive Index: Sine I/Sine R = 1/Sin C = Real depth/Apparent depth = c1/c2
 * Critical Angle: The angle whose angle of incidence is 90 when light goes from
   a denser to a rarer medium.
 * Total Internal Reflection: When light travelling from a denser to a rarer
   medium strikes the second medium with an angle of incidence greater than the
   critical angle, it is reflected... (More)
