Snell's Law Flashcards
1
Q
What is Snell’s law
A
The relationship between the indices of refraction are f 2 media and their angles of incidence and refraction
2
Q
What is total internal reflection
A
When light travels into a LESS DENSE medium, the refracted ray bends AWAY from the normal
3
Q
As the angle was of incidence increases…
A
The angle of refraction approaches 90 degrees
4
Q
When the angle of refraction is 90 degrees…
A
The refracted ray disappears
Angle of INCIDENCE is known as the critical angle
