Galileo Galilei Physics

Improved Essays
We listen to music and hear sound in our everyday lives, whether we are listening to the music in our car, or we are listening to the sound the vacuum makes when it is turned on. Sound and music however, are not a simple concept in physics. There are so many topics and under 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 …show more content…
Galileo Galilei was one of the scientist that studied sound during the 1500’s (“sound”). To some people even say he is one of the greatest scientist especially for the topic of sound (“sound”). People claim this because Galileo was able to show the pitch of a sound was calculated by how often sound waves passed (“sound”). Although Galileo Galilei made a great contribution to the understanding of sound he was not the only one to contribute to the discoveries. Leonardo DaVinci was one of those who contributed greatly to these discoveries. In particular he discovered that sound moves in waves (“sound”). Another important contributor was Marin Mersenne who was the first man who successfully calculated how fast sound was while travelling through the medium, air (“sound”). The person who discovered that a medium was indispensable for sound waves, was Robert Boyle (“sound”). Yet another important scientist who not only contributed to the studies of sound was Sir Isaac Newton. He learned that all sound’s speed was affected by the medium it travels through (“sound”). He also learned other aspects of mediums and how they affect sound. The final scientist I will discuss is Daniel Bernoulli, and he made discoveries about frequencies …show more content…
One of the things that requires math when talking about sound is the speed of sound. The formula for this is exactly as it is when calculating the speed of any other concept; the distance divided by the time will give you the speed. Something that affects the speed of a wave is the medium, which is critical in determining the speed of a wave. If a medium has elastic characteristics, the speed will be less than an object with inertial properties.
Sound and music have plenty of vocabulary terms one of which is frequency. Frequency is how often a wave passes through a medium. Frequency is measured in Hertz or Hz- for short. Basically one hertz equals one vibration each second. The pitch of sound is related to frequency in the same manner. What I mean by this is that the higher the pitch the higher the frequency. Sound is measured is measured in decibels or dB- doe short. A waves length is called a wavelength in this wavelength there is a crest, and a through. The crest is the high part of the wave. On the other hand, the through is the lowest point of a wave.
In conclusion sound and music is very useful during our everyday lives and would not lead the lives we do today if it weren’t for sound and

    Amplitude is a metric method associated with hearing. It is commonly grouped with intensity, loudness, or volume. Apart from amplitude, another thing worth noting about sound waves is their pitch, also called their frequency. Soprano singers make sound waves with a high pitch, while bass singers make waves with a much lower pitch. The frequency is simply the number of waves something produces in one…

    Galileo Galilei was born in Pisa, Italy in 1564 during the Renaissance.This was a rebirthing period in Europe started off in Italy for art, philosophy, and sciences. The Renaissance brought back many ideas from Ancient Greece and Rome introducing many scientists like Galileo. Attending the University of Pisa originally going to study medicine, he was taught the Aristotelian view on the world, later questioning it making way for many of his greatest discoveries. He was an outstanding astronomer, physicist, philosopher and mathematician where he played a leading role in science during that time. Galileo is probably mostly known for his telescopic discoveries, but one cannot forget about his marvelous contributions to physics.…

    When a note is played on an instrument, due to the physics of the sound waves, we don’t hear only that tone that is played. We also hear the played tone as the fundamental, as well as a combination of its harmonics sounding, at the same time. After Pythagoras discovered harmonics, many more explored the idea more thoroughly. At least two unassociated men took significant steps in defining harmonics. The first of these is Marin Mersenne (1588-1648), a French theologian, philosopher, mathematician, and music…

    For example film can record a wider spread of colors on a spectrum than we could see. Because light is a wave oscillates electric and magnetic fields it can be identified as an electromagnetic wave. Electromagnetic waves vary depending on frequency and the wavelength. There is a wide range of wavelengths in the electromagnetic spectrum which its frequency ranges from 1020 Hz to 106Hz. Transverse waves is an Electromagnetic wave theory of oscillating electric and magnetic field.…

    Dmitri Mendeleevs development of the periodic table is the foundation of chemistry. The periodic table has contributed to the experiments and discoveries of many famous chemist such as Joseph Proust who studied chemical compounds and created the law of definite proportions or Robert Boyle who studied the characteristics and behavior of gases. Dmitri Mendeleevs periodic table has also made a major impact on modern day science. The periodic table has helped chemist find missing and unknown elements. In the biography on Dmitri Mendeleev it says, “Scientists continue to adjust the periodic table as new elements are found.…

    DYNAMICS- The degree of loudness or softness in music. Dynamics describe the loudness or softness of the tones, which are measured in decibels and depend upon the physical phenomenon of the amplitude of vibration. TONECOLOR- the characteristic of tone that allows us to distinguish a pitch played between two different instruments. It can also distinguish the differences the quality of tones produced by the same source. RHYTHM- Comprises the recurring pulses and accents that created identifiable patterns.…

    Frequency is the number of cycles occurred in one second, measured in Hertz. Amplitude is the height of the wave, and it is a measure of the amount of force applied over an area, expressed in Newton per square meter (N/m2). Amplitude is directly related to the acoustic energy or intensity of a sound, which is the amount of acoustic energy transmitted across unit area per second, expressed in Watts/surface area. Both amplitude and intensity are related to sound's power. Assuming a sound wave as an expanding sphere of energy, power is the total amount of kinetic energy contained on the sphere’s surface .…
