When the angle of incidence is greater than 43° with the normal, light is totally reflected at the boundary of the water and air. This special angle is called the critical angle. It differs for each two adjacent media that the light passes through. For the boundary of glass and air it is about 48°; for the boundary of a diamond and air it is about 24°. This is the principal utilized in fiber optical instruments. 4. Fill a straight glass tube with water. Seal one end with some type of kitchen plastic wrap. Shine a flashlight from one end and look at the other end of the tube. Does light travel down the tube so that you can see it coming out the
