Understanding Snell's Law Through Practical Activities

This activity on pg.72 explores Snell's Law with practical steps. Learn to draw normal lines, measure incident rays, find refracted angles, and calculate refracted rays in glass and water using the specific substance indices. Make sure your calculator is in degree mode! Enhance your understanding of optics and refraction through hands-on learning.

  1. Activity, pg 72

  2. Snells Law: • The subscripts (1 and 2) correspond to specific substances:

  3. 1. Draw the normal nair = 1.00 nglass = 1.50 The normal is 90° from the boundary between glass and water

  4. Next Step: Measure the incident ray nair = 1.00 nglass = 1.50

  5. Next Step: Draw the reflected ray Find the refracted angle with this equation: Make sure your calculator is in degree mode! For the first angle of refraction : n = 1.000 Angle of refraction 17° nair = 1.00 nglass = 1.50

  6. Next Step: Draw the Normal nair = 1.00 Path light would take with no refraction nglass = 1.50

  7. Next Step: Calculate & Draw the Refracted Ray nair = 1.00 Path light would take with no refraction nglass = 1.50
