As light enters a medium that is more optically dense......
As light enters a medium that is less optically dense.....
Refraction diagram:
Things we need to remember about diagram:
What is the speed of light in a vacuum or in air?
What does the refraction index (n) tell us?
How do we work out refraction index?
What is the refraction index of air?
What is Snells law of diffraction?
if n1>n2 , this means light will bend....
If n2>n1 , this means light will bend....
Diagram to show locations of θ1 and θ2:
What is the critical angle?
If the angle of incidence is smaller than the critical angle then....
If the angle of incidence is equal to the critical angle then.....
If the angle of incidence is larger than the critical angle then....
Critical angle diagram (θ1 = θc) :
Total internal reflection diagram (θ1 > θc) :
How do we work out the critical angle?
What are the conditions of total internal reflection?
What other law applies to total internal reflection?
If n1 = 1.33 and n2 = 1.00 , find θc
