For this standing waves worksheet, students read about standing waves, their nodes, their anti-nodes and their wavelengths. They are given diagrams of harmonics and the equation to find the frequency of harmonics. Students match terms related to standing waves to their definitions, they label a diagram of a standing wave, they calculate frequency and periods of waves and they analyze a graph of a standing wave.
In this wave worksheet, students use Slinky's to observe the properties of waves. They observe longitudinal waves, transverse waves, traveling waves and standing waves and record their observations. They calculate the frequency and velocity of the waves and answer 3 questions about their data.
This wave and electromagnetism assignment is so thorough, it could be used as a unit exam. The first section of it covers wave concepts. The next section addresses static electricity. There is a section that deals with electric circuits. Finally, the worksheet finishes off with magnetism, specifically electromagnetic induction. Though many of the questions require problem solving and computation, the answers are presented as multiple choice. Neat diagrams are included in many of the questions.
Physics masters figure out the wavelength of different waves. Looking at a wave graph, they identify different characteristics. Many more problems get them working with both electromagnetic and sound waves. There are a total of 17 multiple choice questions on the topic of waves.
The casual voice of the filmmaker explains standing waves using a linked chain bordering a neighborhood parking lot, a bucket of blue-colored water, and a rope tied to a fan blade. He uses the appropriate vocabulary (frequency, wavelength, antinode, and resonance), but fails to explain all of the terms. This could be useful for simply demonstrating standing wave motion, but ideally you would have your physical scientists create them in the lab rather than just watching them online. Also, be aware that the shaky video quality and the muffled sound of wind blowing are a bit distracting.
Students study definitions of wavelength, wave speed, wave amplitude, and wave period using an interactive JAVA environment. Distance and time are given so speed=wavelength/period can be verified or deduced by students. Waves reflection and standing waves can also be explored.
An incredibly colorful PowerPoint presents all the facts and definitions about waves that you could need for beginning physical scientists. There are several useful links to online animations of wave action. This may have been produced by a student, but it is still a nice piece that states the important information clearly and will definitely keep the attention of your class. You may want to prepare a question sheet with a sequence related directly to this slide show.
Students differentiate the properties of longitudinal and transverse waves. In this physics lesson, students calculate CEENBoT's rate of propagation by measuring its frequency and distance per cycle. They use a mathematical formula to calculate speed, frequency and wavelength.
Students analyze wave patterns for guitar notes, chords and groups. In this sound wave lesson, students measure and compare ratios of string length to the harmony of the note sounded. Students listen to a song and watch an oscilloscope to chart the relationship between sound and wave length generated.
In this waves worksheet, students experiment with a 'Wiggler' to study the relationship between frequency, period, and the patterns created by the movement of the strings. Students idenitfy how wavelengths relate to frequency and they write a mathematical rule for how they change together. Students use a sound and wave generator to study singing pipes.
Your class will generate their own data relating the number of people to the time it takes to do a human wave. Once data is collected, a line of best fit is found and used to estimate how long it would take for the entire student body to produce one cycle of the wave in the school gym. How fun would it be to actually have your school do the wave and compare the actual time to the calculated estimate!
