3. The tallest person that can see her whole body in a .4 meter mirror is _____________ Draw a picture
4. Light starts in medium x (top) and enters water (bottom) at an angle of 20 degrees. The angle of refraction is 40 degrees. What is the index of refraction of medium x. Draw a picture showing how light would bend as goes from medium x to water.
5. What kind of reflection produces an image? __________
6. What kind of reflection doesn’t produce an image? __________________ Why?
7. Measure the angle of incidence ______ and the angle of reflection. ______ (hint: draw normal first)
8. In refraction, if the angle of refraction is smaller than the angle of incidence, what does that tell you about the speed and index of refraction of the second medium? faster? slower? same?
a. if the angle of refraction is greater than angle of incidence? - second medium is faster? slower? same?
b. if the angle of refraction = angle of incidence? - second medium is faster? slower? same?
