When your eye is submerged in water, is the bending of light rays from water to your eyes more, less, or the same as in air?
Refraction (bending) is much less if the eyeball is submerged in water. That is why you need goggles to focus clearly under water
Well, when it comes to the bending of light rays in water, I have to say it's a bit of a "depth perception deception." You see, when your eye is submerged in water, the bending or refraction of light rays actually increases compared to when they pass through the air. So, in water, the bending is definitely more pronounced. Just remember, even though your vision may be a bit wavy underwater, it's still a great opportunity for all those amusing "fish-eye" selfies!
When your eye is submerged in water, the bending of light rays from water to your eyes is more compared to when it is in air. This phenomenon is due to a property of light called refraction. Refraction occurs when light passes from one medium to another with a different optical density, causing the light rays to change direction.
Water has a higher optical density compared to air, which means that light travels slower in water than in air. As light passes from water to your eye, it slows down and changes direction, resulting in a greater bending of the light rays. This is why objects underwater often appear closer and distorted compared to when they are in air.
So, when your eye is submerged in water, the bending of light rays from water to your eyes is more pronounced than in air.
When your eye is submerged in water, the bending of light rays is more compared to when they pass through air. This phenomenon is due to the difference in the refractive indices of water and air.
To understand why light bends more when passing from water to your eye, you need to know about refraction. Refraction is the change in direction that occurs when light passes from one medium to another. It happens because the speed of light changes as it travels through different materials with different refractive indices.
The refractive index of a medium is a measure of how much it can bend light. The higher the refractive index, the more the light rays bend. The refractive index of water is higher than that of air. Therefore, when light travels from water to your eyes, it experiences a larger change in speed and direction, leading to a greater bending of light rays compared to when they pass through air.
This behavior of light can be explained using Snell's law, which states that the ratio of the sines of the angles made by the incident and refracted rays with the normal to the interface of two media is equal to the ratio of their refractive indices. In this case, as the refractive index of water is higher than air, the angle of refraction is greater than the angle of incidence, causing a larger bending of light when passing from water to your eyes.
In conclusion, when your eye is submerged in water, the bending of light rays from water to your eyes is more compared to when they pass through air.
