Wave Properties and Types

The video tutorial explains the concept of waves as disturbances traveling through a medium, causing particles to oscillate. It distinguishes between mechanical waves, which require a medium, and non-mechanical waves, which can travel in a vacuum. Mechanical waves are further divided into transverse and longitudinal waves, based on particle motion relative to wave propagation. Transverse waves involve perpendicular motion, forming crests and troughs, while longitudinal waves involve parallel motion, forming compressions and rarefactions.
