In this picture, I am plucking a chord on a violin. This is an example of simple harmonics and waves. The chords on a violin, or any stringed instrument, act as strings that are fixed at both ends. The vibration on the string, which was caused by me plucking it, is known as a standing wave, meaning it has nodes at both ends. The nodes are clearly seen as places where the amplitude is always zero. The antinodes are where the amplitude varies from zero to the maximum value. The first harmonic, or fundamental frequency, is seen in the picture. A wavelength is characterized as node to node to node. Therefore, for the first harmonic, the wavelength, ʎ, is equal to 2L, L being the length of the string. Since standing waves follow the standard relationship
Decreasing the tension from high to the next notch in between high and low did not change the amplitude of the wave, but did decrease the wavelength.
Short Story Essay Josh Blume Period 4 “A Mother’s Trials” In many stories the characters have to overcome a certain conflicts. In the short story of “Average Waves In Unprotected Waters” by Anne Tyler; the character of Arnold's mother must overcome two major conflicts throughout the story. The first of these two major conflicts is man vs. self.
Subject: Love Theme: They both make tough choices out of love for the betterment of the other person; Both stories offer a self-sacrifice for the other person’s gain. The Present vs. Average Waves in Unprotected Waters. Great writers create great themes. Simon Rich and Anne Tyler do this in “The Present” and “Average Waves in Unprotected Waters”.
A 45-year-old male comes into the emergency department with symptoms of acute dizziness, dyspnea, chest pressure, and palpitations. He states that he feels that his heart is “racing.”. He has a history of hypertension (HTN) and coronary heart disease (CAD) status post one bare metal stent. He is currently on clopidogrel, aspirin, metoprolol, and Llisinopril. His BP blood pressure is 87/60 mmHg, pulse heart rate 160–-170 beats/min, respirations rate 26 breaths/min, oxygen saturation 90% on room air, and afebrile. His physical exam has pertinent positive findings of diminished global breath sounds and rapid sinus heart sounds. He has no jugular venous distention (JVD), abdominal tenderness, nuchal rigidity, lower extremity swelling, or focal
The wavelength of the wave the distance between the peak of one wave and the peak of the next, between the minimum of one and the minimum or the next, or between any two points the encompass one complete wave cycle. Equivalently, this is the distance the wave travels from when say the electron is at the peak of its motion and the next time it gets to the peak of its motion. Either way this is about 10 or so grid points.
Hi Margaret, I feel that you did a fantastic job of explaining both terms age (pg.53) and gender (pg.51). I can see what you mean when referring to an older generation or “sliver surfers” (pg.53) using social media as a way to receive news. This I feel is especially true since most news stations will post news updates frequently online more often than waiting for the news on the television. I think that although used quite frequently mediated communication (pg.53) is extremely important. We all have such a great amount of information available to us. I agree that males seem to use more rough language than females do usually. More than likely these males are young just as you have explained. Additionally, I found your post to be
As a wave moves into shallow water, the friction created from the wave rubbing against the ocean floor causes the crest of the wave to curl forward. The crest continues to curl forward, until the wave crashes onto the shore.
In the book The Wave by Walter Mosley the crank caller that haunts Errol Porter nightly sounds a lot like his deceased father who died a long time ago when he was small. Enough so that one day Errol goes to the cemetery one night in response to the to the one called the "Caller". He finds a man that does indeed resemble his father, except this man is much younger. All of the stories the the caller has told Errol Porter has match to the ones of his Father, but how can Errol’s father rise from the dead and turn back the clock?
My quarter one project depicts a surfer from the side view of a wave, as she is in motion of walking up to the nose of the board. Although my drawing did not have a deeper meaning to it, the image meant a lot to me as surfing is a big part of my life and a major influence to my art. My drawing was based off of an influence from Ray Pettibon, a popular ocean artist. I think one of the most successful parts of my piece is the amount of motion I show in the waves much like Pettibon, as well as the human figure that seems as if in motion as she crosses her legs. I struggled with creating a three dimensional look of the wave, which I did not fully accomplish, but I am happy with the outcome. My desired viewer takeaway is that they do not get confused

String instruments, such as a guitar and violin, make their musical sounds when the musician either plucks the
Let’s look at one other wave property of light. Light travels in transverse waves and this property is demonstrated by a phenomenon called polarization. Polarization means that the waves of light are restricted in their direction of vibration. Think of a horizontal string that you shake from one end. If you shake the string up and down, you will get up and down, or vertical, waves. If you shake the string back and forth, you will get horizontal waves. In this way, the string is said to be polarized. Vibrating electrons emit waves that are also polarized. A vertically vibrating electron emits light that is vertically polarized and a horizontally vibrating electron emits light that is horizontally polarized.
What is a sound wave? A sound wave is produced by a mechanical vibration, such as a tuning fork. The vibrating object causes the surrounding medium, such as air, to vibrate as well.The wave travels through the medium to a detector, like your ear, and it is heard.As with any type of wave, a sound wave is also described by it's wavelength, amplitude, period, and frequency.
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.
Wave by Sonali Deraniyagala is a life taking memoir where Sonali watched her whole family be swept away before her eyes being the only one to tell her tale. Throughout the book Sonali deals with depression and anxiety after finding out what was the cause of her family's death, A tsunami. She later explains her feelings and difficulties without her family being by her side. Relying on friends she slowly gets better by facing the one place she wanted to forget ,Sri Lanka. This was just the beginning for Sonali.
