Web2 days ago · The pacific ocean surface, which can be considered a convex mirror, forms a virtual image of the moon. What is the diameter of that image? 10. A british company makes optical fibers that are 13.6 km in length. If the critical angle for the fibers in air is 42.1°, what is the index of refraction of the fiber material? WebIn optics,the law is used in ray tracing to compute the angles of incidence or refraction,and in experimental optics and gemology to find the refractive index of a material.The law is also satisfied in metamaterials,which allow light to be bent "backward" at a negative angle of refraction with a negative refractive index. chipotle teacher appreciation
