Wave Properties and Measurements

This video tutorial explains the wave equation, focusing on its components such as wavelength, frequency, and velocity. It describes how to measure wavelength from crest to crest or trough to trough and discusses frequency as the number of wavelengths passing a point per second. The tutorial includes a problem-solving example where a sound wave's speed, wavelength, and period are calculated using given data. The video concludes with a detailed explanation of how to calculate the period of a wave as the inverse of frequency.
