Crystal reflectivity

Webentertainment, information and products to stimulate your imagination, satisfy your curiosity and enhance your creativity Webangle of incidence reflectivity is close to zero R ~ 0. This angle is called the Brewster's angle θ and is associated with the refractive index n of the material through equation 1 (2): Θ B = arctan (n/n 0) where n 0 is refractive index air (n 0 =1). To determine the values of the refractive index, we measured
