I explain the definition of harmonics in standing waves and show their shapes and patterns for strings that have 2 fixed ends, 1 fixed & 1 open end, and 2 open ends. I show how to find wavelength, velocity, frequency, and the fundamental frequency.
0:00 The velocity in a medium is constant
1:16 What is a harmonic?
3:06 2 fixed ends: reflection
5:02 2 fixed ends: wavelength of harmonics
6:49 2 fixed ends: frequency of harmonics
9:40 Example problem: 2 fixed ends
11:30 Fixed at 1 end: reflection
13:45 Fixed at 1 end: wavelength, frequency, & harmonic #
17:20 2 open ends: reflection
17:59 2 open ends: wavelength, frequency, & harmonic #
