This video tutorial covers the identification and calculation of wave properties, focusing on amplitude and wavelength. It provides examples of how to measure these properties in different wave scenarios, including both transverse and longitudinal waves. The tutorial explains the concepts of amplitude as the height from the undisplaced point to the peak and wavelength as the length of one complete wave cycle. It also discusses methods for counting waves and calculating wavelengths in complex wave patterns.

What is the amplitude of a wave if each box represents 15 centimeters and the wave height is one box?

• 25 centimeters

• 20 centimeters

• 15 centimeters
