Refraction of Light: as it passes from more dense to less dense mediums

when light air and water meet

The angle and wavelength at which the light enters a substance and the density (for example passing from water into air), the light is refracted (or bent) away. 1) at right angles to the mirror located at the point where the rays meet. two different materials such as the surface between air and water, or glass and water. The person on the end will meet the water and slow down first, then the next person in The same thing happens to a light ray when it moves from air to water.

A ceremony involves stereotyped bodily movements, often in relation to objects possessing symbolic meaning… Ceremonies express, perpetuate, and transmit elements of the value and sentiment system and… they intensify the solidarity of the participants. From the New Columbia Encyclopedia The Classical Greek philosophers divided the world into four elements—earth, air, fire, and water.

In the Chinese tradition there are five elements—earth, air, fire, and water, plus wood or paper. In the Indian Buddhist tradition, the world is also composed of five elements—earth, air, fire, and water, plus space. Each of these five elements is paired with one of our five senses: The last element, empty space or the void, corresponds with sound and hearing.

WaterFire incorporates all of these elements from these traditional systems into a new harmonious whole. As WaterFire begins, the empty void is invoked through the striking of a large gong, which heralds the setting of the sun, the lighting of the fires and the beginning of the music for the evening. Music from all over the world and the gentle percussion of the crackling fires add a rich accompaniment to the more familiar sounds of urban life. An unexpected operatic aria blends with the wind, or a lingering minor chord from a nocturne intermingles with the sound of rippling water.

These juxtapositions heighten our awareness and intensify our experience of our surroundings. The elements water and fire are obviously the heart of the sculpture installation. When a ray passes from air into glass the direction in which the light ray is travelling changes.

The light ray appears to bend as it as it passes through the surface of the glass. When a light ray passes from air into water a similar thing occurs: This 'bending of a ray of light' when it passes from one substance into another substance is called refraction.

The bending of a ray of light also occurs when the ray comes out of glass or water and passes into air. What causes this bending? Glass and water are thicker and heavier than air.

They are said to be 'denser' than air. What happens is that light slows down when it passes from the less dense air into the denser glass or water. This slowing down of the ray of light also causes the ray of light to change direction.

So what happens to the light when it goes from one medium to another? Light changes speed Imagine that you and your friends are at the beach. You all decide to swim together, so you link arms and approach the water as a straight line.

So imagine that you approach the water at an angle relative to the shoreline. The person on the end will meet the water and slow down first, then the next person in line, then the next, until everyone is walking through the water. You can say that the water bends the path of of each individual toward a normal line drawn perpendicularly to the shoreline, since the people still on the shore are bent further away from the shoreline than those in the water.

The same thing happens to a light ray when it moves from air to water, or from any fast medium to a slow medium: Least time principle Another way to think of this is to imagine you and your friend are racing out to a raft in the middle of a lake.
