The video tutorial covers the concept of waves, including their definition, types, and properties. It explains how waves transport energy through a medium and distinguishes between transverse and longitudinal waves. The tutorial also discusses wave properties such as amplitude and wavelength, and explores the relationship between wave speed, frequency, and wavelength. Practical examples and calculations are provided to illustrate these concepts.

What is the definition of a wave?

• A disturbance that destroys energy

• A disturbance that carries energy through matter or space

• A form of light only

• A sound phenomenon only
