Показать описание
This physics video tutorial provides a basic introduction into mechanical waves. It contains plenty of examples and practice problems. It discusses how to calculate the period, amplitude, wavelength and frequency from a sine wave graph. It explains how to calculate the wavelength from the frequency and the speed of the mechanical wave on a string. One practice problem explains how to calculate the wave speed on a string given the tension force applied to the string. It mentions how to calculate the linear density or mass per unit length of the string and how to calculate the wavelength given frequency. The last problem is on standing waves. It explains how to calculate the fundamental frequency, the frequency of the third harmonic, and the frequency of the fifth overtone. In addition, it mentions how to determine the number of nodes and antinodes from a given harmonic / overtone.

2:40 = Amplitude formula
3:35 = Period/Frequency formula
4:50 = velocity of the wave formula/ first velocity equation
5:35 = linear density formula
6:25 = Velocity of a string formula/ second velocity equation
7:45 = Fundamental Frequency of a wave formula
9:45 = nodes and antinodes formula
11:10 = wavelength formula

I'm not so sure about the node thing jut because my teacher doesn't count the "first" node
