Experiment 7: Velocity of Sound Laboratory Report Hazel Guerrero‚ Kyle Iddoba‚ Matthew Jocson‚ Thea Lagman Department of Biological Sciences College of Science‚ University of Santo Tomas Espanya‚ Manila Philippines Abstract Verification of the relationship between frequency of sound and its wavelength and the determination of the velocity and the speed of sound in different mediums was the main focus of this experiment. The speed of sound and its velocity was determined using the resonance

Lab Sheet 1. In the lab activity‚ you will examine sound waves as they are emitted from a moving source. Predict what will happen to the sound waves when the sound source is in motion. Record your prediction (hypothesis) as an “if then” statement. (For example: If you select the GO button‚ then the train will move) If the sound source is moving‚ as it get closer to the person it will get louder and the farther away it gets it starts to fade. 2. Select the boy icon. Select the lowest pitch by selecting

The coming of sound was an innovation to cinema that forever changed the way films were produced‚ viewed and performed. Sound plays many roles in the way a film is narrated and perceived by the audience. Sound‚ as defined in the Oxford Dictionary of Film Studies‚ ‘is central to the way in which a film establishes setting‚ shapes character‚ signposts its narrative‚ directs the audience’s and instils general emotional states’ (2012: 385). Sunrise: a song of two humans by F.W. Munrau was released in

Edgar Allen Poe has wrote many poems two are “The Raven” and “Eldorado” two poems wrote in the 19th century. Each with a theme that means lots of things to different people and in many ways they are different and in some they are the same. These poems have different speakers but have the same author who just wants to share his creativity and sorrow with the world. One poem talks about losing a loved one while the other talks about searching for your whole life to find something that you can’t find

different ways of how sound particles react in many different situations. Some are able to have high chances of interaction such as reverberation and echoes‚ while other venues forced the sound to distribute or even be absorbed. Many areas the class had been taken through also had large capabilities of reflecting sound completely. The class was taken through two studio rooms; Studio A and Studio B. Also‚ the class had the opportunity to witness the mechanics of sound as it traveled

Title: Measuring the speed of sound. Research question: How to determine the speed of sound by using the relationship between the frequency of the signal generator‚ f and the length of air column in the tube‚ l . Variables: Manipulated | Frequency of the signal generator‚ f | Use different frequency of signal generator which are 1000Hz‚ 1400Hz‚ 1800Hz‚ 2000Hz‚ 2500Hz‚ 3000Hz and 3600Hz. | Responding | Length of air column in the tube‚ l (±0.5cm) | Measure the

r.A Sound of Thunder by Ray Bradbury Imagine being able to travel back in time. Many writers have explored this idea in science fiction stories and movies. You are about to read one of the most popular_and thought-provoking_stories about time travel ever written. LITERARY FOCUS: STYLE AND MOOD A writer’s diction‚ or word choice‚ greatly defines a work’s style. Style is also determined by sentence length and complexity. A story that is written in brief simple sentences‚ for example‚ is different
