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