It seems that your question refers to a selection of pictures (A, B, C, D) that illustrate how light behaves when it transitions from air to water. However, since I can't see the images, I can describe the general behavior of light when it moves from air (a less dense medium) to water (a more dense medium):
-
Refraction: Light travels slower in water than in air, which causes it to bend. When a light ray enters water at an angle, it will change direction towards the normal (the imaginary line perpendicular to the surface at the point of entry).
-
Snell's Law: The bending of the light can be described by Snell's Law, which relates the angle of incidence (the angle the incoming light ray makes with the normal) to the angle of refraction (the angle the ray makes with the normal after entering the water).
If you can describe the options A, B, C, and D, I can help you identify which one represents the behavior of light accurately.
