Physics III: Vibrations and Waves
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

Vibrations and waves are everywhere. If you take any system and disturb it from a stable equilibrium, the resultant motion will be waves and vibrations. Think of a guitar string—pluck the string, and it vibrates. The sound waves generated make their way to our ears, and we hear the string’s sound. Our eyes see what’s happening because they receive the electromagnetic waves of the light reflected from the guitar string, so that we can recognize the beautiful sinusoidal waves on the string. In fact, without vibrations and waves, we could not recognize the universe around us at all!

The amazing thing is that we can describe many fascinating phenomena arising from very different physical systems with mathematics. This course will provide you with the concepts and mathematical tools necessary to understand and explain a broad range of vibrations and waves. You will learn that waves come from many interconnected (coupled) objects when they are vibrating together. We will discuss many of these phenomena, along with related topics, including mechanical vibrations and waves, sound waves, electromagnetic waves, optics, and gravitational waves.

0.0 stars

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"New technologies for enhancing electronics and photonics are crucial for emerging applications in energy, sensing, artificial intelligence, and countless other areas. But these technologies are hard to come by using traditional semiconductors. Over the past decade, so-called third-generation semiconductors have proved to be a boon to materials science and engineering, giving researchers increased versatility in boosting device performance. Among the most promising properties of these materials is piezoelectricity—the ability to convert mechanical energy to electrical energy and vice versa. The December 2018 issue of the MRS Bulletin takes a look at how researchers are exploiting piezoelectricity in semiconductors to enhance electronic and photonic devices like never before, providing a glimpse into the world of piezotronics and piezo-phototronics. In 2006, Zhong Lin Wang’s group at Georgia Tech discovered that piezoelectricity in zinc oxide nanowires exerts a gating effect like that in transistors..."

The rest of the transcript, along with a link to the research itself, is available on the resource itself.

Polarized Sunglasses
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

In this activity, learners explore how polarizing sunglasses can help diminish road glare. By rotating a pair of polarizing sunglass lenses or other polarizing materials, learners will discover that some angles are better at reducing glare than others. Learners observe light from the sky, reflected from a mirror, or reflected from the surface of a pond. Use this activity to introduce learners to principles of light and polarization.

Radiating Charge
Unrestricted Use

Rating
0.0 stars

The electric field lines from a point charge evolve in time as the charge moves. Watch radiation propagate outward at the speed of light as you wiggle the charge. Stop a moving charge to see bremsstrahlung (braking) radiation. Explore the radiation patterns as the charge moves with sinusoidal, circular, or linear motion. You can move the charge any way you like, as long as you don���������t exceed the speed of light.

Student groups rotate through four stations to examine light energy behavior: refraction, magnification, prisms and polarization. They see how a beam of light is refracted (bent) through various transparent mediums. While learning how a magnifying glass works, students see how the orientation of an image changes with the distance of the lens from its focal point. They also discover how a prism works by refracting light and making rainbows. And, students investigate the polar nature of light using sunglasses and polarized light film.
