Understanding Waves: Transverse and Longitudinal

The video tutorial explains the concepts of waves, focusing on transverse and longitudinal waves. It covers the basic properties of waves, such as crest, trough, amplitude, and wavelength. The tutorial also discusses wave equations, including how to calculate wave speed using frequency and wavelength. Transverse waves are described with examples like water and electromagnetic waves, highlighting their perpendicular oscillations. Longitudinal waves are explained with examples like sound waves, emphasizing their parallel oscillations and regions of compression and expansion.

What is the top part of a wave called?

• Wavelength
