dc.description The observation that a stick partially plunged into a pool of clear water looks as if it is bent (figure 1) probably goes back to time immemorial. The more sophisticated interpretation of this observation as being due to the bending of light rays on passing from one medium (air) to another (water), as well as the law governing the angles which the rays make in the two mediums relative to a normal drawn perpendicular to the surface separating them (figure 2), has been discovered several times throughout history – first by the Arab, Ibn Sahi, in 984 AD, then by Thomas Harriot in 1602, then by Willebrord Snellius or Snell (figure 3) in 1621, and lastly by René Descartes (figure 4) in 1637. en_US
