Curated OER
Standing Waves
In 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...
Curated OER
HW Unit 10:6-Standing Waves
In this standing waves worksheet, students answer 9 questions about graphs of various waves. They identify standing waves and their nodes, anti-nodes, wavelengths, amplitude, frequency and number of cycles.
Curated OER
Harmonic Frequencies
In this waves worksheet, students make the nodes, antinodes, waveform, and wavelength for harmonics shown. Students complete 11 fill in the blank questions and 10 problems to solve.
