Wave power

1. Explain the difference between periodic and aperiodic waveforms. What are the visual differences? What are the characteristic sonic qualities of each? (2 points) Answer: A periodic waveform has repeatable patterns. Also, periodic waveforms have a tone. Most musical instruments have repeating periodic waveform. The periodic waveforms can also be found in bird sound and human vocal voice. However, an aperiodic waveform dose not have a repeating waveform and tone, like noise, the engine idling…

Polyphemus said, “how dare they come onto my island! I must gather my foot power to stomp on these fools who decided to bare their scrawny human bodies onto my island! Brother Sam! I command you to stay on the lookout for any other people who dare to step foot onto my island.” Polyphemus wandered through the bright green trees; each one springing at least 60 feet high. He got to his home filled with everything he needs to gain the power he needs to stomp on the humans and make them pay for what…

the same tune as when young. In like manner, the interval increases until a perfect pitch is heard. In this paper we will examine both the mathematics and music background for these ideas. We will examine the Fourier series representations of sound waves. Furthermore, we will see how they relate to harmonics and tonal color of instruments. The goal in this paper is aimed at exploring…

So the bigger the objective lens, the more light can be collected. If you want to increase the light gathering power by 4, you can double the diameter of the lens. How bright the image is depends on how an image can spread over a big area of a lens.The bigger the area, the less bright an image, and the smaller the area, the brighter an image would be. In a telescope, the magnifying power is the ratio…

loud voices. The blue salty ocean waves pushing against the sand and the wind whistling in your ear very loudly. Loud music playing from the giant black jukebox in the background.…

the time at the beach we were playing in the sand and the shallow water. Then I and my cousin Nic decided to ride the waves with tubes. I got a little to far out and my aunt called for me to come closer as I was swimming back I was facing shore as I was almost where my aunt wanted me my cousin Nic screamed: "Ciana look out". As he said look I turned around and about a fifteen-foot wave took me under the water. While I was under the water all the water got in my mouth and I was under for about…

matter, which is a solid, liquid or gas. Sound travels in longitudinal waves. There is also a vibration that starts on an object, and this causes a vibration on all the molecules. When these molecules vibrate, they cause all of the other surrounding molecules to vibrate. This vibration will spread from molecule to molecule causing sound to travel. 1. What is a wave? A wave is a chain of vibrating molecules. In general, a wave transfers energy from one place to another. 2. Can sound move through…

The earthquake also resulted in loss of power and water in the city of Illapel. Furthermore, the earthquake caused hundreds of millions of dollars in damages and left 9000 people homeless. Over one million people had to be evacuated in order to prevent more deaths. Therefore, it can be predicted…

those are subtopics. These topics include waves, which is what we will be focusing on today. Sound waves are made very easily, in fact we create them every day. They can be created by smashing two cooking pans together, this is because as the pots hit each together they create vibrations. Music can also be made is a more complex way. Music is made by repeating sounds in a pattern. Although we cannot see it, waves transport energy. Sound has waves and these waves can be…

A. WAVES Normally when energy is transferred from one place to another a disturbance is involved. Waves can travel through air, water, and solid materials. Mechanical and electromagnetic waves are the two types of waves. Medium is the material in which a wave travels. Mechanical Waves When a source of energy causes a medium to vibrate, a mechanical wave is formed. Mechanical waves require a medium to travel. There are two different types of mechanical waves: longitudinal and transverse waves.…
