435 wordsWe have at least a television in our home. television allows us to hear and see events as soon as they happen. If our grandma's mother or father see TV, they " ll suprised and say 'This is diablo's machine!'. We watch TV at least two hour in a day. HOW WORKS TV When a TV program is broadcast the sound and picture are sent out simultaneously by two different radio systems. The TV camera takes the picture. Camera is the most important part of the camera. The light from the object is allowed to fal...
Next Group Of Light Waves
491 wordsIn this universe there are many thing that we cannot explain. Among these many things is light. Light, as far as we know, come in different wavelengths and the size of the wavelength determine what type of light it is. The middle wavelength lights are what gives us the seven basic colors of red, orange, yellow, green, blue, indigo and violet. Beside these visible lights there are the lights that cannot be seen by the human eye. These invisible lights can be grouped into two other groups the long...
Light And Sound Waves
532 wordsSounds are produced by the vibrations of material objects, and travel as a result of momentum transfer when air molecules collide. Our 'subjective impression' about the frequency of a sound is called pitch. High pitch has high vibration frequency, while low pitch has a low vibration frequency. A pure musical tone consists of a single pitch or frequency. However, most musical tones are "complex summations" of various pure frequencies - one characteristic frequency, called the fundamental, and a s...
726 wordsColour Physics 712 words 1. Colour physics, dispersion of sunlight into colours of the spectrum. (Sir Isaac Newton 1676) Discuss and illustrate Newton's experiments and beyond, from particle to wave theory. 2. Research, identify and illustrate how the eye sees colour, reference to light emitted, transmitted and reflected. 1. Sir Isaac Newton, held the theory that light was made up of tiny particles. Around the same period, Christiaan Huygens, believed that light was made up of waves vibrating up...
Radio Waves And Light Waves
2,156 wordsThe electromagnetic spectrum is made up of six different types of waves. Radio waves, Microwaves, Infrared waves, Visible light, Ultravioletlight, X-rays and Gamma rays. The radio waves are used to transmit radio and television signals. The infrared waves are used to tell temperature of areas. Visible light is all the colors that we can see. Ultravioletlight can help things grow but to much can cause diseases such as skin cancer. X-rays are used as a tool to find broken bones or take pitchers of...
Wave Particle Theory
653 wordsBinary reasoning limits our knowledge for it oversimplifies the subject being studied. Computers operate in binary mode, that is they only can understand a 1 or a 0, and this fact is what makes artificial intelligence so hard to achieve. The fact that humans can work outside of simple duality is what distinguishes us from other animals and machines. Certain issues cannot be studied on their integrity unless they are looked upon without using the "two-valued logic" system. Two examples would be: ...
Light Wave Particle Properties
878 wordsLight is what we see. It can be thought of either as a particle, (the photon), or as a wave. The photon we can easily think of as a small dot travelling through space at the speed of light. Each photon has a particular colour or energy. But how do we think of light as a wave For this we need to know that light is also an "Electro-magnetic field" - a combination of electric-field and magnetic-field - the same thing that causes static electricity and magnets to attract (or repel) things. Light is ...
Gabor's Theory About Light Waves
1,123 wordsToss a pebble in a pond -see the ripples? Now drop two pebbles close together. Look at what happens when the two sets of waves combine -you get a new wave! When a crest and a trough meet, they cancel out and the water goes flat. When two crests meet, they produce one, bigger crest. When two troughs collide, they make a single, deeper trough. Believe it or not, you " ve just found a key to understanding how a hologram works. But what do waves in a pond have to do with those amazing three-dimensio...
Objects Via Light
318 wordsHolography is the process of storing information reflected off objects via light and using that information to produce a photograph of that object. The photograph has characteristics that bear striking resemblance to that of the real object. Unlike regular photographs taken, holograms can show the observer different perspectives of the object rather then just the front of an object (Jeong & Knowles, 1978). The main developments and discoveries dealing with holograms started with Dennis Gabor. By...
