Wave Properties and Light Refraction

The video tutorial covers fundamental concepts of wave physics, including amplitude, wavelength, frequency, and wave velocity. It explains how these properties are interrelated and how they change when waves travel through different media. The tutorial also discusses the effects of refraction on wave properties, emphasizing that frequency remains constant while wavelength and wave velocity change. The video concludes with a call to action for viewers to engage with the channel.

What is the primary focus of the video introduction?
