Exploring Wave Properties and Characteristics

The video tutorial introduces waves, explaining their types, properties, and behaviors. It covers mechanical and electromagnetic waves, transverse and longitudinal waves, and properties like frequency and amplitude. The tutorial also discusses how waves change direction through reflection, refraction, and diffraction. Finally, it highlights real-world applications of waves in engineering, such as in microwave ovens, x-ray machines, and tsunami prediction.
