Average Index of Refraction for the Liquid __________

 

Conclusion

1.   Write down SnellŐs Law.

2.   Explain why only two pins may be used to find the angles of incidence and refraction when using a semi-circular dish.

3.   Explain why the light ray leaving the curved side of the dish did NOT refract.
