Reflection and Refraction

Today's class, we quickly went over the answers on our assignment nos. 5-8 on the 2nd green booklet. Then we spent almost all of our time watching the video of Reflection and Refraction. Ms. K gave us white sheet to answer while watching and went over it after watching.


Here are the answers for 5-8 on the green booklet:


5. λshallow= 1.1 cm


6. a. n= 1.33


b. Vdeep = 4 cm Vshallow = 3 cm


c. = 22°


7. angle of refraction= 36.9°


8. Vr = 5.6 km/s
