1. ITMO 540 HOMEWORK 3 Name: Payal Desai CWID: A20362549 REVIEW QUESTIONS: Answer 1: White noise is the static noise that is heard in the background. Some amount of it is always present but too much of white noise does not enable a clear conversation because we lose the signal. Answer 2: Impulsive noise is the one which occurs discretely.

The three most important properties of a wave are the wavelength, the amplitude, and the frequency. The wavelength is the distance from one point on a wave to the next identical point on the next wave. The amplitude is the distance from a waves rest position to either the crest or trough of the wave. The frequency is a rate which represents the amount of times a wave repeats

Wave properties: Frequency: How many waves go past a point in one second; measured in hertz (Hz). The higher the frequency, the more energy in the wave. 1 Ask the children to play 'verbal tennis' in partners on words that describe sounds (eg loud, quiet, vibration, pitch). One child says one word related to sound, then their partner says another and so on. 2 Ask the children what things make sounds.

The objective of this piece was to create something meaningful to me, that will flow together well by using audio files. I’m a huge fan of the piano, so I knew that I wanted to incorporate a piano in the piece. Surprising enough the main part of the whole piece is the pinaoloop2 on a loop. The work process for this piece primarily involved getting the audio samples that will work nicely around my main piece which is the pianoloop2. After obtaining the audio files, the major software that I use to get the sounds together was Audacity.

“Waves transmit energy, not water, and are commonly caused by the wind as it blows across the ocean, lakes, and rivers” ( Megan Forbes, 1). Odysseus has obtained Poseidon’s wrath, and number one rule is to not

First of all, what type of wave is light and sound? Light and sound are not the same types of wave. There are 2 types of waves and light is a transverse wave while sound is a longitudinal wave. Source D states, “Longitudinal waves are waves whose direction of vibration is the same as their direction of travel…. Transverse wave is a moving wave that consists of oscillations perpendicular to the direction of the energy transfer.”

On each of these signals it is fitted, in red, an harmonic pulsating pressure:

Juan Perez Mrs. Banks 26th November, 2015 English Honors 9 Block C Thesis Statement: The Seafarers Bridge is the most exquisite bridge in Australia because of its style, size, and in some cases bridge type. The bridge has a very sophisticated design. Is not to amazing.

DAY BY DAY A Long Walk To Water (ALW) and The Big Wave (TBW) are two books that share the same themes but in different situations and circumstances. Jiya( the protagonist of TBW) and Salva ( the protagonist of ALW) go through many challenges. These stories are based on true events and both protagonists face major obstacles. In both stories we learn about perseverance, motivation of loss, and selfishness. Both characters decide to stick with friends and family.

(Assume the friction between the air track and PAScar is negligible) (1 point) Once the string is cut the PAScar will continue to move on the track with a constant velocity and no acceleration. The hanging mass would be in free fall and its acceleration would be that of gravity. Conclusion With the use of vectors and the force table, I was able to balance the ring in the middle of the table, and figure out what components were necessary to cancel out all the forces that were acting upon it.

It was the opposite, with the lowest frequency tuning forks that caused resonance at a higher length. There were many observations, calculations (wavelength, the speed of sound, and percent area from actual speed of sound), a graph comparing the length of two different tubes, and analysis questions. The results of the data showed that the tuning forks with the highest frequency had the shortest tube length. For example, for the 512 Hz of the open-open tube, the distance was .335m and the open-closed tube had .300m. This resulted in the wavelength to be the lowest also. Therefore, the lowest frequencies had the largest tube distance and wavelength.

The ocean… The sound of the waves applauding and hugging the shore. The internal sounds of the body out in the world’s biggest swimming pool. The echo of my sister’s laughter. The salty smell so strong that one can taste it dancing on ones taste buds.

[3] This pattern is also linked to Equations 1&2 as stated previously. The position of every fourth fringe was recorded giving the value which is required in Equation 3 below. (See Table1 for the recorded data) Knowing the wavelength of sodium to be 589nm the angle, ,at the apex between the two glass plates can be calculated using Equation 3 as
