The laser is passing from air into a new medium in each image. Which medium has a higher index of refraction, A or B? How do you know? * Medium A has a higher index of refraction because it is a lighter color.
Medium B has a higher index of refraction because it is a darker color.
Medium B has a higher index of refraction because the laser beam bends more.
Medium A has a higher index of refraction because the laser beam bends less.
