Unformatted text preview: location of images underwater-In order to observe the fiush from outside the water a transmitted ray must enter your eye.-- You will think it comes from a point obtained by traceing it backwards-- Extend any 2 of the many many transmitted rays from the nose of the fist backwards to find the image of the nose of the fist (where they intersect)-the location of the image will be the same for any observer outside of the water. Fig 2.49-The precise amount of bending is determined by the law of refraction ( sometimes called Snell’s law. Total internal reflection is an extreme case of a ray bending away from the normal as it goes from a higher to a lower index of refraction medium (from a slower to a faster medium....
