To practice Tactics Box 18.1 Analyzing refraction. If a ray refracts between medium 1 and medium 2, having indices of refraction n1 and n2, the ray angles θ1 and θ2 in the two media are related by Snell's law, n1sinθ1=n2sinθ2. This law becomes a central idea in a procedure for analyzing refraction problems, as explained in the following Tactics Box. Draw a ray diagram. Represent the light beam with one ray. Draw a line normal to the boundary. Do this...

QUESTION If the water is replaced by a transparent fluid with a higher index of refraction, the critical angle of the fluid- air boundary is: O smaller. o the same as for water. o larger PRACTICE IT Use the worked example above to help you solve this problem. (a) Find the critical angle for a water-air boundary if the index of refraction of water is 1.33. (b) Use the result of part (a) to predict what a fish will see...

Partner: Date Name 11 Snell's Law Introduction When light passes from one material to another it is always bent away from its original path. This process is known as refraction and the change in direction depends on the change in optical density (or refractive index) of the two materials. A larger change in refractive index results in a larger change in angle between incoming and outgoing light beams. A light beam bends closer to the normal in the material with...
