Electromagnetic Model Of Light, Refraction And

The documentary Visions of Light was made for the purpose of showing the art of cinematography. Cinematography was defined throughout the film as the making of a motion picture. “I found out that I was unconsciously responding to light.” said by Ernest Dickerson an American film director and cinematographer. Light is thought of to be something so little but means so much in a film. It is used to change the emotion and to tell people where to look.

Light is a form of energy that behaves in some ways like waves. Light waves have a range of wavelengths. A wavelength is the distance between any point on one wave and the corresponding point on the next wave. Different wavelengths of light appear to us as different colors. Light that contains all wavelengths in the same proportions as sunlight appears white. See LIGHT.

While implementing Primary Health Care models, identical to those in metropolitan areas, in a rural setting is not practical, I feel there is an obvious need to improve primary health care in remote areas. This is due to the significant health gap between Indigenous and non-Indigenous Australians, in rural and remote areas

The atom of an element has electrons that are found around the nucleus in regions known as orbitals. When energy is absorbed by the electrons of an atom they begin to jump to higher energy levels. When this happens the electrons are in an excited state. However when the electrons begin to release the energy and drop in energy levels they emit electromagnetic radiation. If the radiation that is emitted falls between 400 to 700 nanometers then the electrons emit photons which we can see as visible light.

1-14 Bellringer 2: Incandescent bulbs give off a warm glow. The researchers created a bulb that still had filament in the center, but was surrounded with a new kind of filter that sits around the filament.

If light is shone at various mediums with varying densities then the light will bend more with different speeds, wavelength and angles. Learning about bending light is important because when the aliens invade our planet earth they will bring, as NASA predicted, tons and tons of light based weapons. In order to stop the aliens you need to know how to bend the deadly light away from our planet for it to be saved. A computer was used to simulate light being shone through water, air, glass and prisms.

Electromagnetic radiation behaves both as particles (called photons) and as waves. Wavelength () and frequency () are related according to the equation

The sensory energies of light and vision and sound vibrate as waves passing through space. These waves result from reflected light or from changes in air pressure caused when vocal cords and other stuffs move. Generally eye and the ear identified the waves as light and sound. The waves of light and sound can describe in term of wavelength, frequency and amplitude. Wavelength is the distance from one peak of the wave to the next. Frequency is the number of complete waves or cycles that pass a given point amount of time. Amplitude is height of the wave from baseline to peak. These are shown in the Figure 3. The different wavelength, amplitude and frequency makes various sound and vision experience.

In this third experiment, I used different colors of filters within the laboratory and see how the wavelengths of light

The refraction of light demonstrate that change of direction which light travels is caused by a change in speed of light. There will be a change in wavelength when light changes the direction it is traveling, which will then change the speed of light. The Refraction of Light Wave: Base on the diagram below, light travels from air into water, the light refract, causing the speed of light to slow down, making light continue to travel at a different direction. The change of direction is called refraction, as light enters from a less dense medium to a denser medium, light should refract (bends) more towards the normal line. Note:

In this experiment, paper chromatography was used to determine what pigments were present in spinach extract. From this experiment, we can see that four different types of pigments are present in the spinach extract used, the following are those pigments: chlorophyll a, chlorophyll b, beta carotene, and xanthophyll. The absorption and reflection of these pigments all revolve around the basis of the electromagnetic spectrum. The form of electromagnetic radiation is released as light and overall it is a type of energy that travels in waves. Going back to the spectrum itself, all the different types of electromagnetic radiation combine to form the electromagnetic spectrum, which tells us which colors can be absorbed and/or reflected. Each wave

Certain squids and crustaceans use bioluminescence to make clouds of luminescence to repel predators IV. Appearance/ Colors A. Color is based on the chemistry 1. What causes what colors B. Land animals mostly bioluminesce in green or yellow colors, sometimes red. 1. fireflies C. Ocean animals mostly bioluminesce in blue-green or green colors 1.

Natural and artificial light have varying properties that affects their capability and appropriateness these properties regularly impact their surroundings. Natural light comes in a spectrum of colours, which are the visible rays. Also on the colour spectrum are shorter wavelengths, named ultraviolet rays and higher wavelengths, known as infrared rays. Both of these are not visible to us. Exposure to the sunlight can help

If asked what light is, one could say that it's one of the most basic

With today’s science, light becomes more specifically perceived as a spectrum. The specific name for this spectrum is the electromagnetic spectrum, which contains many types of waves (NASA, Electromagnetic Spectrum). In Figure 2, the spectrum shows a variety of wavelengths with specific wavelengths classified by its length. The range of wavelengths humans can see wavelengths that are around 400 – 700 nanometers (nm) as colors while all other electromagnetic waves are simply blind to humans. The interesting classes for light that are used to measure are microwave and infrared light. The laser is
