Why does the change in the speed of light change its direction while in water?

It seems to me that, to understand that, you need an understanding of the Huygens-Fresnel principle. Check the corresponding Wikipedia article; it has a nice illustration that shows how refraction is derived from this principle.

How does the speed of light change when it enters the water?
That would depend what it enters from. If the light is transitioning from air to water,its speed decreases. If it's going from jello to water, its speed increases.
What happens to speed of light from water to air?
It speeds up. Air and water are both media (plural form of medium). Each one of them has a different speed of light. As the incident ray passes from air to water, it refracts to be closer to the normal. A refraction occurs when there is a change in the speed of light. A change in the speed of light occurs when there is a change in media. In this case the media is changed from air to water. The second medium (water) must also have a lower speed of light in order for refraction to occur
Where do the light waves change speed from a pencil?
ACTUALLY ! Its when the pencil enters the water .
Is it possible to travel at the speed of light in water?
The speed of light in water is less than the speed of light in space. Only light can travel at the speed of light.
What does speed change when a ray of light leaves air and enters a piece of glass?
The speed of light slows down ... in general, the denser the material, the lower the speed of light. (For example : air to water to glass.) The maximum speed is in a vacuum.
What happens when light passes into water?
The light will change directions (to be closer to the normal) once it hits the water. This is known as refraction which is a property of light. In this case, you have 2 media (plural form of medium). The two are air and water. The reason it changes direction is because air allows a different speed of light than water. Water is denser which is why light can't travel as fast. This change in the speed of light is what causes the light to change direction once it hits the water. In conclusion, after light hits the water, it will change directions (to be closer to the normal) due to the fact that the medium is changed(from air to water) which results in a change in the speed of light.
Why does a pencil look broken when placed in water?
Refraction will make the light change direction, when it changes from water to air.Refraction will make the light change direction, when it changes from water to air.Refraction will make the light change direction, when it changes from water to air.Refraction will make the light change direction, when it changes from water to air.
Can light go through water?

What is refracted light?
The refraction of light is the change in direction of a light ray when it crosses a boundary between two transparent substances. Refraction of light is the change in direction of a light ray due to a change in its speed as it goes from one medium to another.The speed and wavelength of a light ray change when this occurs, but the frequency remains the same.When light travels from denser medium to rarer medium it moves away from the normal [line at right angles to the boundary] and when light travels from rarer to denser it moves towards the normal.
Bending of light as it passes through water?
Yes, light bends as it enters water. This is known as refraction of light. It is the change in direction of a wave due to a change in it's speed. Water has an index of refraction of 1.333 and air has an index of refraction of 1.From Wikipedia:In optics, refraction occurs when light waves travel from a medium with a given refractive index to a medium with another. At the boundary between the media, the wave's phase velocity is altered, usually causing a change in direction. Its wavelength increases or decreases but its frequency remains constant. For example, a light ray will refract as it enters and leaves glass, assuming there is a change in refractive index. A ray traveling along the normal (perpendicular to the boundary) will change speed, but not direction.
How does the speed of light change when it enters the water?

What happens when light waves pass from air into water?
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
What will happen when light ray passes from water to glass?
Well in physics we know that when a wave crosses from one medium to another there is a change of speed. For all light rays, this change of speed is annotated by a change of direction. So given that air is less dense than water, then you would certainly expect the speed to decrease as it moves from the air into the water. And given that this change in speed is accompanied by a change in direction, the ray of light would then move towards the normal (an imaginary line that is perpendicular to the plane surface). To extend this further, if you would want to calculate the change in speed you can do this with the following equation. To get the change in speed: We know that the refractive index of air to water is |1.3| so by means of the equation Speeda/Speedb=1.3 speed a is speed in air (3 X 10 to the power of 8) and speed b is the speed in water. So by substituting 3 X 10 to the power of 8/speed b=1.3 Speed b= 3 X 10 to the power of 8/1.3 By calculating you get the answer to be speed b= 2.3 X 10 to the power of 8 (speed of light in water)
Can energy change an object?
yes it can like when it temperature of a pot of water, or it can change the direction and speed of a baseball.
Why does a beam of light change direction when it enters water?
Because it slows down when entering water.
Why does the beam of light change direction when it enters the water?
Because it slows down when entering water.
Why do objects look distorted under water?
A ray of light will change direction when going out of water, into the air. This is called "Refraction".A ray of light will change direction when going out of water, into the air.
