The Effect Of Light On The Human Ear

Water is a medium for metabolic reactions and an important constituent of cells. In most plants and animals, it makes up about 65-95% of their mass. The water molecule is referred to as a dipole, a polar molecule, with a positive (hydrogen) and negative (oxygen) charge, separated by a very small distance. A molecule with a separated charge is polar. A hydrogen bond; the weak attractive force between a hydrogen atom with a partial positive (o+) charge and an atom with a partial negative charge (o-) oxygen can be formed between two atoms. Hydrogen bonds are weak, however in large quantities, like the large number present in water it makes the molecules difficult to separate and gives water a wide range of physical properties vital to life.

Professor John Blamire of brooklyn.cuny.edu describes a single water molecule, the smallest part of a chemical element or compound that still shares the same chemical properties as defined by whatitis.com, as two 'slightly ' positive hydrogen atoms and one ' slightly ' negative atom together forming a hydrogen bond. In a water molecule, hydrogen atoms have a single electron and oxygen atoms have six electrons. The hydrogen atoms attach at a 107.5 degree angle and each share two electrons, one of theirs and one of the oxygen atom 's, to attach and

All electromagnetic radiation is a form of light, but human eyes can only detect visible light. Theories suggest that light is an electric field tied up with a magnetic field, flying through space. In the visible light spectrum, each color moves at its own wavelength. Light waves are similar to sound waves but light waves move much faster than sound waves. The color of an object is determined by the color light that is being reflected.

Light waves are a form of electromagnetic waves, which consist of patterns of electric and magnetic energy. The visible spectrum is only a small part of the electromagnetic spectrum-the

What special bond (in water) opposes water’s molecular movement when water absorbs energy requiring water to have more heat added to raise its temperature? Hydrogen Bond.

When light is absorbed the electrons get excited and go into a higher energy level, so it move much more freely. This produces an electrical

(Click Slide) Another unique property of water is its high specific heat capacity. Due to the strong hydrogen bonds that exist between water molecules, a lot of energy is needed to break down the bonds. As the Particle Theory states, particles move faster and further apart when heated. This is why water helps maintains a moderate temperature on Earth and different bodies of water, crucial for the survival of organisms.

In water, Hydrogen bonding pulls molecules close together by the negative oxygen made by another molecule of water is attracted to a positive hydrogen atom. Thanks to hydrogen bonds, water boils at 212 degrees Fahrenheit instead of -108.4 degrees. Hydrogen bonds are also make up proteins and DNA (wisegeek). Covalent bonds are bonds between two non-metals that share electrons with one another. Covalent bonds occur when they have similar electronegativity (diffen). An Ionic bond is where a metal and a non-metal bond when the metal gives up electrons to complete the outer shell of a non-metal, and then an attracting another with the now polarized atoms (differencebetweenExplain the 7 characteristics of life.In order for something to be considered a living being, they need to follow a set of seven rules. The first is that living things are made of cells, either single celled or multicellular. The next rule says that a living thing must have both molecular and cellular organization on several levels. Multicellular beings must have tissue, organs, and organ systems to be considered an organism. Livings must use energy for maintenance and growth; Energy can come from other

Soon after Einstein discovered that light was a particle he wrote a paper in which he described light as a wave. It turns out that light is a collection of photons which travel as an electromagnetic wave. This explains how light can be both a wave and a

The intermolecular forces in water contain hydrogen bonds, and the difference in electronegative of oxygen and hydrogen that gives them different charges.

Let’s look at one other wave property of light. Light travels in transverse waves and this property is demonstrated by a phenomenon called polarization. Polarization means that the waves of light are restricted in their direction of vibration. Think of a horizontal string that you shake from one end. If you shake the string up and down, you will get up and down, or vertical, waves. If you shake the string back and forth, you will get horizontal waves. In this way, the string is said to be polarized. Vibrating electrons emit waves that are also polarized. A vertically vibrating electron emits light that is vertically polarized and a horizontally vibrating electron emits light that is horizontally polarized.

The wavelength gets shorter when you shine it through glass more than water because the more dense the medium is the wavelength becomes shorter. Also, when you shine a beam of light through a prism it would reflect of one of the sides which creates an angle and it also separate the light and forms into a

When air is mechanically disturbed, sound waves are created. Sound waves enter the ear canal causing the eardrum and a series of three small bones in the middle ear to vibrate. This vibration is carried further into the inner ear (or cochlea) which is filled with fluid. As the fluid vibrates, tiny hair cells in the cochlea sway and bend, resulting in the generation of electrical impulses which are carried to the brain via the hearing nerve. The brain interprets this as sound and characterises the sound by its pitch (frequency) and volume (intensity).

First, let’s talk about polarization. Light waves, whether they’re from the sun or from an artificial light source, will vibrate and radiate outward in all directions. When its vibrations are aligned into one single plane of direction, the light is said to be polarized. You see natural polarization every time you look at the sun’s reflection on the surface of water. The reflected glare off the surface is light that did not make it through the “filter” of the water, and that’s often why you can’t see anything below the surface, even if the water is crystal clear.

Chapter 6 was an interesting read which taught about the physical properties of water and how water is the most used solvent as it can dissolve almost any substances. Water is made up of a chemical compound of two hydrogen atoms and one oxygen atom. Waters are constantly moving and in a process called the hydrologic cycle. This cycle is uses solar radiation to gain energy. This process will help to produce clouds from raising vapors, which will eventually carry rain or snow.
