Refraction of Light

Refraction of light

Image formation by convex Lens

• Note that the critical angle is an angle of incidence value. 
• For the water-air boundary, the critical angle is 48.6-degrees. 
• For the crown glass-water boundary, the critical angle is 61.0-degrees.
•  The critical angle for the crown glass-air boundary,41.1 degrees

 = sine-1 (nr/ni) = invsine (nr/ni)

• The ratio of nr/ni is a value less than 1.0. 
• TIR only occurs if the refractive medium is less dense than the incident medium, the value of ni must be greater than the value of nr.
