What is Ultrasonic testing and how does it work?

The use of ultrasound for non-medical purposes is more common that I  thought.  It is used for many applications not limited to aerospace,  automotive, construction, manufacturing, environmental protection,  purification of water, decontamination of the atmosphere and soil, and  several other remediation applications. There is a study of the effects  of ultrasound on materials. This is known as sonochemistry.
To find more applications it is easier to research Nondestructive  Testing (ultrasonic) and you will find companies that specialize in the  use of ultrasonic testing for finding the thickness and faults including  corrosion in pipe. It is a non-destructive method using several methods  but primarily pulse-echo through transmission from something that emits  the sound wave and something to receive it (probe). This can very  accurately find faults in the material in a noninvasive way. Say you  have a large steam line in a factory and are unsure of the damage of  oxidization that has occurred in the lines, it would be easier and maybe  more cost effective to hire a company to evaluate before disassembling  and planning on re-piping if unneeded. I only think of this application  because I currently work in an older manufacturing plant, and we have  some steam piping in use that we really have no way of knowing its  density and integrity without shutting down the system and taking it  apart and reassembling. We often must plan for the worse and have parts  on hand and it can be unnecessary. Once again, I am finding these fields  of study fascinating. I hope you all are enjoying your research!

Explore the physical principles of classical physics.

Assignment Content
Competency
Explore the physical principles of classical physics.
Student Success Criteria
View the grading rubric for this deliverable by selecting the “This item is graded with a rubric” link, which is located in the Details & Information pane.
Instructions
In a two-page paper, identify the classical physics principles contained within the following scenario. Explain how these principals connect to work done by Galileo or Newton. Finally, consider the different fields in which Galileo and Newton did research, and give an example of one of these fields in use in your life. For instance, Newton developed the field of optics. If you wear glasses or contact lenses, you are using Newton’s physical optics theories every day. Aside from glasses or contacts, how do the theories of Newton or Galileo affect you in your daily life?
Scenario
Mandy took a trip to Rome, Italy. She gazed out over the open ocean 20,000 feet below as her airplane began its descent to her final destination. She could watch the Sun setting in the west. Over the Eastern horizon peeked a full moon, just rising, displaying its cratered face. As the plane neared the ground, Mandy could not help but think that she was in a giant metal object hurtling through the sky. Without the specific shape of its wings, the plane would fall to the ground no differently than a large metal projectile.

Identify the use of the scientific method in a modern physical problem.

Assignment Content
Competency
When possible, synthesize content from the individual course modules. Your content should expand, elaborate, and evolve from the activities in the individual modules, and coalesce to present a cohesive message to the viewer.
Student Success Criteria
View the grading rubric for this deliverable by selecting the “This item is graded with a rubric” link, which is located in the Details & Information pane.
Instructions
Using any slide share or movie making software, you can utilize information gathered throughout the course to create a visual travel log. This multi-media presentation will include images, video, and voice over dialogue consisting of a mix of research and original content that demonstrates your analysis of course concepts. The movie will be accompanied by a paper that supplies the dialogue for the visuals of your film.
You may use examples of physics principles in use in everyday life that you previously gave as examples in Modules 01-06, but you cannot reuse the same wording as used in previous modules. For example, if you had mentioned using glasses for Module 03, you can once again bring up that concept here, but you cannot read from your Module 03 submission paper.
Requirements

Three-minute video in MPEG-4 format.
Original voice over (written) dialogue and accompanying paper.
Images that help “tell your story.”
30 seconds of original video connecting your experience to your topic.
Narrative concept
Imagine you are a writer for Physics Today (or insert whatever physics pop journal you wish), and you are to create a travel vlog for your an overseas trip. In your presentation, your editor wants you to include all relative physics concepts that you encounter in your journey.
For the heart of the presentation, your editor has deemed it essential to address the following core issues and questions:
Identify physics principles in various real-world examples.
Identify the use of the scientific method in a modern physical problem.
Identify the use of classical physics principles in relation to a real life situation.
Identify physics principles in various real-world examples, and connect to your own experience.
Identify physics principles in various real-world examples and modern technology.
Identify a technology that uses quantum mechanics, and connect to your own experience.

How is the sound you hear different from someone in a car traveling next to the tracks at the same velocity?

While traveling in the engine of a train, you are given the opportunity to activate the horn.  How is the sound you hear different someone near the tracks ahead of your train? How is the sound you hear different from someone in a car traveling next to the tracks at the same velocity?
This week, you will study the relationship between sound and the material in which the sound wave is disseminated. The speed of sound in one material may be greater than in another material due to changes in material properties. For example, a material’s rigidity and/ or density can play a role.
Sound waves and mechanical oscillations are common in many types of phenomena that you encounter daily. Musicians have an understanding of the characteristics of the sounds produced by their instruments, and this could create new ways for them to be creative with their art. Sonograms are used in technology, and ultrasounds are vitally important in medicine. Seismographs and sonar are sound wave-based technology that allows scientists and engineers to study the characteristics of the earth and under the sea. Technology-based on sound waves is used to enhance and improve our lives in many ways that are not obvious. In this unit and discussion, you will explore the science behind sound waves and their applications
