Waves, Sound and Light

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

It doesn’t matter if someone is blind or deaf for one to see what is all around they have to use other senses no one knows exist until the time is needed for one rely on it. One learns to rely on other senses to survive once one sense fails. However, teaching someone who can see and hear how to use their other senses can be complicated if they are not receptive to the teacher, or in other cases teach a person to see beyond their normal sight to open up their senses.

In the background, I heard something fall to the floor. Although I knew this was my cats’ doing, I did not check to see what mess they had created and continued to put my clothes in the washing machine. After I had added detergent and assorted my clothes, I cranked the dial and noticed for the first time that I could hear every click that the dial made, in addition to the water beginning to fill. It usually takes about twenty minutes for my clothes to wash, so I checked the clock and planned to move my clothes from my washer to my dryer once they were done washing. Once I was finished, I walked to my couch and I heard my feet patting my kitchen floor with every step that I took. This was a huge eye-opener for me. It made me realize that Deaf people are not able to hear the sounds around them, nor the sounds that they make themselves. If I was not able to hear my cats, washing machine, dryer, or alarm, I would become incredibly discouraged. It is obvious that I depend heavily on noises to alert me. Instead of taking action to make sure things are taken care of, I rely my ears to do the work for me.

People say naturally that the only way there's a sound is if you can hear it. Now, based on the two passages, 'Hearing Sound does not Require Ears' by Tabitha Callaway, and 'Sound is All around Us' by Jason Torres. Which state that sound there without us being able to hear it. As well as you not even needing ears to hear in the first place.

Sound is usually something that people usually take as something simple. However, sound can be a very complicated topic. Sound is a wave of vibration (called a longitudinal wave) caused by a release of energy.

Sound is very interesting and has many topics to discuss on what systems we use to understand all of it. Humans brains are very important for sounds and vibrations but so are our ears. Ears are how we hear and gather sounds and our brain is used for understanding and processing all of the sounds and vibrations we have previously

What do you think when you hear sound? Do you think of the old tale that says if a tree falls in the woods and no one is around to hear it, does it make any noise? Or do not question it and move on with life. Believe it or not sound is everywhere. Sound works in many different ways, to fully understand it, let's break it down into three main pieces. First of all sound is energy, next sound can change, Lastly to hear and to understand are two different things.

The bending of waves as they pass from one form of matter to another is refraction. When light travels from an object to one’s eyes, it makes the object seem to be in a different location. As waves access a new medium. they travel at a different rate in the alternative medium. For instance, light waves travel at a lower rate in water than in air. The

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.

Also in the article " Hearing sound does not require ears ", Tabitha Callaway states "Snakes do not have ears and do not have any openings that can take in the sound, but they do have parts inside of their bodies that are still able to receive the vibrations that sound makes." This is saying that the brain can still understand sound even if you do not recognise it or even if you can not

2009 Mami Zoe Taylor and her brother Zack Taylor are in Miami and they are just having lunch. Zoe is a nice and kind girl. She has brown curly hair sometime in braids and she is 16. Zack is one of the nicest brother, I met. He loves to play video games a lot , he is only 11. When they finished lunch, they heard a noise like someone was banging on a wall or something like that. Store when they got up and payed the bill and went to the boom store. The boom store is a smooth jazz place with a rock and roll section, it has many musical instruments that Zoe and Zack like. Zoe loves to play the violin so she tries the violin and she likes it. So they went back home and ask her mom and dad if she and get the violin and they said “yes you can Zoe.” Her mom said and when she Said yes they heard that rumbling noise again. But it was the food in the oven.

Life is a museum of sounds. Everywhere you go, special symphonies can be heard. Whether it's the rumbling base of the cafeteria at lunchtime, the peaceful orchestra of the forest, or the high pitched flute of young children playing, sounds are everywhere. But what if you were blind to these amazing things? How would it feel to see all the world's marvels, but not fully experience them?

Directions: Sketch the motions of the waves and fill in the table below for each trial.

The color wheel relates the wavelengths of transmitted light to absorbed light. Objects absorb different amounts of white light, which is what makes an object have its unique color. The white light is what in turn makes color. While there were many theories throughout history on light, the first theories about light were created by the Ancient Greeks. These theories tried to describe light as a ray which moved directionally to a point. Pythagoras was best known for his theorem of the right triangle that was made up of the assumption that vision was made from light rays that came out of a person's eye and hit an object. This is true in many senses. In reflection, when light hits a smooth surface, it hits then bounces off. A reflected ray always comes off the surface of a material at an angle equal to the angle at which the incoming ray hit the surface. However, when light bounces off a rough surface, light reflects at numerous angles

Light is a form of energy and composed of different wavelengths. When the light exposed to an object, the light could be reflected at the surface of the object (specular or diffuse), and it could be absorbed or scattered within the object, or it could refract or totally transmitted through the object44, 45. The wavelengths (colors) that are reflected, refracted or transmitted are perceived by receptor cells (i.e. rods and cones) in the eye and recognized by the brain as a specific color. The wavelengths of visible light range from approximately 400 to 700 nm45, 46. The wavelengths that are transmitted, refracted or reflected create the color that is perceived and till about the translucency level of the material. If all light is transmitted, the material will appear completely transparent. If all light is absorbed, the material will appear completely opaque, and the color black is perceived. However, if some of the wavelengths of visible light are absorbed and others reflected, refracted, or transmitted, the color that is perceived corresponds to the wavelengths that are reflected, refracted, or transmitted, and the level of translucency is depend on the amount of the light that transmitted through the material9, 44-46. Moreover, the reflection of the light depends on the surface texture of the restoration. Thus, a smooth surface increases the specular reflectance, in which the angulation of light reflection is equal to the angle of the light source. This reveals more of
