Summary: Summarization of what a beat is and how one occurs. Then I go over a couple of questions and detailed answers to the questions.

Summary: In this learning object I describe standing waves and use them to explain the phenomenon of Chladni figures. There is also a brief mention of harmonics or resonant frequencies although more information can be found on pages 226 and 227 of the textbook. For this learning object I used a powerpoint with youtube links included.

Summary: I used a PDF to demonstrate how the Ruben’s Tube is an example of standing waves in music

Summary: Standing waves on strings of guitars and the use of a capo are explained on Powerpoint.

Summary: This Learning Object (via powerpoint) looks at a natural occurrence of standing waves that poses many problems for aircrafts near mountainous regions. By examining these mountainous waves (aka lee waves), this LO targets common misconceptions and demonstrates relationships between properties of standing waves.

Summary: My learning object uses a prezi to explore the concept of standing waves, specifically on how wavelength and frequency are related to the number of nodes over a fixed length of string. I take these concepts and apply them to the violin, using a short video to demonstrate how only certain harmonics can exist on the violin and how we hear the difference between the harmonics, in terms of pitch.

Summary: This power point explains the real life phenomenon of Doppler’s effect and explains it with sample questions

Summary: In this learning object (PDF problem), the iconic superhero known as The Flash experiences several different situations which can be described (and modeled) by the Doppler Effect. The last question in this LO spices things up by throwing Superman into the mix!

Summary: In this learning object, you can learn detailed cases / applications of the doppler effect. Also review the different format of the key equation.

Summary: In this learning objective, we examine the derivation for the equations relating frequency heard by the receiver and frequencies emitted at the source for both receivers moving away and towards the source, using a Prezi. We begin with familiar equations relating period/frequency, velocity and wavelength and manipulate these to allow us to solve the problem. The setting of two moving skaters and a finishing line horn is used as context for this particular problem.

Summary: I used PowerPoint to present about my favourite TV show Sonic Boom, which is about a blue hedgehog named Sonic that can reach supersonic speed and create shock waves and sonic booms! After making this presentation, I now know that if I want to be as cool as Sonic, all I have to do is run faster than sound!

Summary: Use concepts of intensity and power to determine how far one needs to sit away from a crying baby to reduce noise levels.

Summary: This learning object briefly explains power intensity and its measurement. It also describes and emphasizes the importance of protecting yourself from high sound levels. The use of a Powerpoint presentation helped aid the flow in a continuous and an easy to follow manner.

Summary: A crossword on the key terms on Light Waves and Optics.
The answer key is provided on the bottom of the last page.

Summary: Two questions regarding the travelling of sound waves through cold and warm air, presented as a powerpoint.

Summary: A crossword testing recollection of terms terms and understanding of sound waves.

Summary: Brief YouTube video going through what a transverse and longitudinal wave are, along with some examples. The idea is to clarify the concept of transverse versus longitudinal waves.

Summary: As technology advances, more and more ways to fun are being developed. This learning object aims to demonstrate the relationships between properties of a harmonic wave and highlights common misconceptions.

Summary: This Learning Object is a Word document that explores the velocity of a traveling wave through a cord. A diver is about to be attacked by a shark. She needs help from her crewmates and shakes her suit’s umbilical cord. How long will it take for them to notice the motion in the cord?

Summary: Speed of a travelling wave depends on the properties of the medium, and for a particular type of wave (e.g. sound), speed is constant as long as the wave stays in that medium. The relationship v=fl shows that if speed is constant, changing frequency will change wavelength. The example given in this slideshow is how dolphins use echolocation to detect objects in the ocean.

Summary: This learning object reviews relevant words and terms included in WAVES Chapter 14

Summary: This prezi goes over four everyday examples of resonance and how sound is produced and heard as a result of it.
