The speed of light changes as it crosses the boundary between two optical media with different optical densities. The behavior of light traveling across consecutive boundaries is described below: - From Medium A to Medium B: Speed of light increases - From Medium B to Medium C: Speed of light decreases - From Medium C to Medium D: Speed of light decreases If the optical density of Medium D is verified to be greater than that of Medium C, which of the following represents the correct descending order of optical densities of these media?

Which of the following statement(s) is/are true regarding the laws of refraction when a straw appears bent in a glass of water? Statement 1: The incident ray, refracted ray, and normal lie in the same plane. Statement 2: The ratio of the sine of the angle of incidence to the sine of the angle of refraction is constant.
