When light travels fast in a medium, it tends to bend away from the normal. This is known as refraction. Refraction occurs due to the change in speed of light as it moves from one medium to another, causing it to bend towards or away from the normal depending on the speed change.

What is fast light or sound?
"Fast light" refers to light moving at its maximum speed in a vacuum, which is approximately 299,792 kilometers per second. "Fast sound" refers to sound waves traveling at their maximum speed in a medium, which is approximately 343 meters per second in air at room temperature.
What is it about the nature of light that causes it to be refracted?
Refraction is the bending of a wave when it enters a medium where it's speed is different. The refraction of light when it passes from a fast medium to a slow medium bends the light ray toward the normal to the boundary between the two media. The amount of bending depends on the indices of refraction of the two media and is described quantitatively by Snell's Law.
Why does light rays bend?
The refraction of light when it passes from a slow medium (high density) to a fast medium (low density) causes the light to change speed and thus it bends away from the normal to the boundary between the two media. The amount of bending also depends on the indices of refraction of the two media and is described quantitatively by Snell's Law.
How can one determine the wave velocity in a given medium?
The wave velocity in a given medium can be determined by dividing the frequency of the wave by its wavelength. This calculation helps to understand how fast the wave is traveling through the medium.
When light passes from a fast medium to a slow medium is it refracted towards or away from the normal?
Light is refracted away from the normal while passing from denser(slow) medium to a rarer(fast) medium.At one angle called the critical angle the angle of diffraction is 900.After this the ray diffract at an angle greater than 90 i.e. it comes back to the slow medium.Whereas from faster to slower medium the rays bend towards the normal.Thus avoiding the possibility of coming back to the slow medium.

How fast does electricity travel in one second?
Depends on the medium through which it is traveling.

Explain why light bends when it passes from one medium to another?
Light moves at the speed a medium permits. It is "handed off" to each bit of material in turn. One "side" of light encounters the different medium before the other, and so a turn is involved. Think of drivng a car along a road, with one tire on smooth pavement, and the other tire on rough pavement. You have to slightly turn the steering wheel to keep from turning across this interface between smooth (low n, high speed) and rough (high n, lower speed). Light *has* no steering wheel.
What is the difference between refractions and lens?
First lets consider a double convex lens. Suppose that several rays of light approach the lens; and suppose that these rays of light are traveling parallel to the principal axis. Upon reaching the front face of the lens, each ray of light will refract towards the normal to the surface. At this boundary, the light ray is passing from air into a more dense medium (usually plastic or glass). Since the light ray is passing from a medium in which it travels fast (less optically dense) into a medium in which it travels relatively slow (more optically dense), it will bend towards the normal line. This is the FST principle of refraction. This is shown for two incident rays on the diagram below. Once the light ray refracts across the boundary and enters the lens, it travels in a straight line until it reaches the back face of the lens. At this boundary, each ray of light will refract away from the normal to the surface. Since the light ray is passing from a medium in which it travels slow (more optically dense) to a medium in which it travels fast (less optically dense), it will bend away from the normal line; this is the SFA principle of refraction.

What describes how fast a wave moves?
The speed of a wave is determined by the medium it is traveling through and the properties of that medium, such as its density and elasticity. In general, the speed of a wave is faster in a more rigid and less dense medium, and slower in a less rigid and denser medium.
When light would refract?
If one considers reflective indicies, if the reflective index of the second medium (n2) is larger than the first (n1), the ray bends towards the normal. This means that n2 > n1Since n is defined as c/v, we know that the speed of light is greater in the first medium. Thus, when light changes speed from fast to slow, it bends towards the normal.
What does velocity of a wave measure?
