Harmonics

Mr. Anderson explains harmonics in AP Physics Essentials video 116. He uses a guitar to illustrate how harmonics are integer multiples of the fundamental frequency. The video covers standing waves, how wavelength is determined by boundaries and frequency, and how to calculate frequency using wavelength and velocity. Examples and a SimBucket simulation are used to demonstrate these concepts.

What are harmonics and how are they related to the fundamental frequency?

What is the significance of the 12th fret on a guitar in relation to harmonics?

Explain the concept of standing waves and how they are created.

How does the length of a string affect its fundamental frequency?

Describe the relationship between wavelength and frequency in the context of harmonics.

How can you calculate the wavelength of the second harmonic for a given length?

Discuss how the frequency changes as you move up in harmonics.
