A ray of light falls from the air onto the surface of the water. Glass is located under a layer of water. It is known that the refractive index of glass is greater than the refractive index of water. Which figure correctly depicts the path of the light beam?
When passing from an optically less dense medium to an optically denser one, the beam approaches the perpendicular to the surface, that is, the angle of refraction becomes less than the angle of incidence. In this case, the beam can leave the medium at a zero angle, that is, perpendicular to the boundary of the medium, only if it falls at the same zero angle.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
