To keep things simple, let's simply accept that water and air have different densities.
This means that there are fewer molecules per square millimeter.
When light hits an atom or molecule, it must be absorbed then emitted again. This takes time.
This, in turn, means that light does not take as much time to move through air than water. When light enters water from air, it "slows down" and its direction changes as a result. This effect is known as refraction.

When you put a pencil in water why does it look bent?
An interesting property of light called refraction just took place. When light enters the water, it can't move as fast and it has to slow down slightly. It's kind of like how if you are walking, you can walk at a normal speed but if you walk in water, you can't walk quite as fast. If light from the image enters the water straight, then the image looks normal - which was what you originally did when the pencil was straight up and down. If the light enters the water at an angle, then the change in speed between the open air and water causes the light beam to bend away from its original path. When the pencil was at an angle, the image was at a bigger angle in the water than in the air and made the pencil look like it was bent.
Are light rays refracted or bent as they pass from on substance to a different substance?
Yes, and that is called Refraction. This is because the speed of light can vary from medium to medium. The speed of light commonly known is the speed of light at a vacuum.Put a straw to a glass of water and look from above. You may see the straight straw bent at the surface of water, because the light rays that come from under the water are bent when passing the water/air barrier. Because light rays speeds up when entering air from water. This change of speed can change the angle it was travelling.Light is an electro magnetic wave. Electro magnetic waves have the wave particle duality, that it behaves as a energy wave as well as a particle stream. Therefore, em waves also has a mass.
Why can you see a ruler bend in water?
It is because of the way water deflects the light. The image perceived by the retina is a pictorial representation of a reflection of light. Water and air are different mediums through which the electromagnetic light travels through.
Why does a straw appear bent in a cup of water?
A straw looks "bent" when it's in water because water causes light to "change course" when it moves from air into the water. The light will again be caused to change course when it leaves the water to go back into air. This is called refraction. Refraction is a fundamental property exhibited by a wave that changes mediums through which it is traveling.Or, making it simple..A straw seems bent because water is denser than air, so when it changes from air to water is applied it seems bent.
Why is light not visible through a bent pipe?
light does not bend and can not provide sufficent amounts of light in for visibility
What wave property causes a straw to look loke it is bent in a glass of water?
Refraction of light causes the straw to appear bent in a glass of water. Light waves change speed and direction when they pass from one medium (air) to another (water), causing the light to bend at the air-water interface. This bending effect creates the illusion of the straw being bent.
How would you use refraction in a sentence?
The location of the fish in the water is not where it seems to be, due to the refraction of light in the water.
How can you use refraction in a sentence?
Light refraction causes a straw in a glass of water to appear bent or broken.
What causes a pencil to look bent in water?
Water can cause a distortion of the light and in turn causes optical illusions. The water refracts light in such a way that objects viewed through light can appear bent, or angled sharply. This is a function of refraction.
Why does a straw look bent in a galss of water?
When light passes from air into water, it changes speed and direction due to the difference in refractive index. This causes the light to bend or refract, making the straw appear to be bent at the air-water interface.
What light wave is bent the most?
Red light waves are bent the most compared to other colors as they have the longest wavelength among visible light. This property causes red light to refract more when passing through different media, such as air or water.
Why do objects appear to be bent when partially submerged under water?
When light passes from water to air, it changes speed and direction due to the difference in refractive index. This causes the light rays to bend, resulting in what is known as refraction. When we view objects submerged in water from above, the light reflecting off them undergoes refraction, making the objects appear bent at the surface of the water.
Why does a spoon in a glass appear to be bent or broken in water?
When light travels from water to air, it changes speed and direction due to the change in the medium's density. This causes the light rays to refract or bend, creating an optical illusion that makes the spoon appear bent or broken at the point where it enters the water.
Why does a pencil immersed obliquely in water appear bent and short explain?
When light travels from water to air, it changes speed and bends, causing the pencil to appear bent. This effect is known as refraction. The change in speed causes the light rays from the pencil to change direction as they pass through the interface between water and air, creating the illusion of a bent pencil.
A stick appears bent and short when immersed obliquely in water why?
When light passes from water to air, it changes speed and bends (refracts) due to the change in the medium's density. This bending of light causes the stick to appear bent at the water's surface. The apparent shortening is due to the difference in how light travels through water compared to air, creating an optical illusion.
Why does a straw appear bent under water?
When light passes from one medium to another (in this case, air to water), it changes speed and direction due to the difference in optical density. This phenomenon, known as refraction, causes the light rays to bend at the air-water interface. As a result, the straw appears bent when viewed from outside the water.
Why does a straw appear bent when placed in water?
When light passes through water into air, it changes speed and direction due to the change in density. This change in speed and direction causes the light rays to refract, making the straw appear bent at the water's surface. However, the actual position of the part of the straw in the water remains unchanged.
