Whenever light hits a water surface, some of the light is reflected off, and some of it is refracted, or "bent", deeper into the water. The proportion that is reflected and refracted depends on the wavelength of the light and the angle of incidence. When light goes straight down into the water, most of it penetrates the surface and goes into the water. When the light impacts at an angle, more of the light is reflected away.
Water can both reflect and absorb light. When light strikes the surface of water at an angle, some of it can be reflected off the surface due to the difference in refractive indices. However, water can also absorb certain wavelengths of light, which is why the depth of water affects its color appearance.
The angle of incidence always equals the angle of reflection in the law of reflection. This means that the angle at which light strikes a surface is always equal to the angle at which it reflects off that same surface.
When light strikes a transparent medium, such as glass or water, it can be transmitted through the material, absorbed, or reflected. The speed and direction of light can also change when moving from one medium to another, a phenomenon known as refraction.
When a light wave traveling through a diamond strikes a boundary with water at a 45 degree angle, it will refract as it enters the water due to the change in medium density. Some of the light will also reflect off the boundary between the diamond and water, causing partial reflection and transmission of the light wave.
The angle that the incoming light ray makes with the normal is called the angle of incidence.
I dont know so i need help right now!

When a beam of light hits water, it can undergo refraction, which causes it to change direction due to the change in speed between air and water. Some of the light may also be reflected off the surface of the water.
Before a lightning strike, a charge builds up along the water's surface. When lightning strikes, most of electrical charge occurs near the water's surface. Most fish swim below the surface and are unaffected.
The speed of the light wave slows Some light is reflected off the surface of the water The light that enters the water is "refracted" (the direction of propagation changes due to the different indexes of refraction in air and water) Eventually the water will absorb all the energy of the light if the water is deep enough
Light passes through water by entering the water, slowing down, bending due to the change in optical density, and continuing to travel through the water until it reaches the surface or an object that absorbs or reflects the light.
The light hits the water at the same time and therefore the light can't bend. Where as if the light hit at a different angle then it would another hit the water at the same te and therefore it would bend.
