Refraction
Refraction ,[object Object],Medium (plural “media”) - the material that is being used or undergoing a process
Refraction ,[object Object]
Refraction ,[object Object],[object Object],[object Object]
Refraction in Water ,[object Object],[object Object]
Speed of Light ,[object Object],[object Object],or
Refraction ,[object Object],[object Object]
Index of Refraction ,[object Object],(since units cancel, a refractive index does not have any units) or
 
Given : Speed of light in glass = 1.91 x 10 8  m/s Speed of light in vacuum = 3.00 x 10 8  m/s =  1.57 The refractive index is 1.57 = 3.00 x 10 8  m/s   1.91 x 10 8  m/s
Given : Refractive index in water = 1.33 Speed of light in a vacuum = 3.00 x 10 8  m/s v  = 2.26 x 10 8  m/s The speed of light in water is 2.26 x 10 8  m/s 1.33 = 3.00 x 10 8  m/s   v
