This video tutorial covers the basics of waves, focusing on how they transfer energy. It distinguishes between mechanical and electromagnetic waves, explaining that mechanical waves require a medium while electromagnetic waves do not. The tutorial further explores the two types of mechanical waves: transverse and longitudinal. Key wave properties such as crest, trough, wavelength, and amplitude are discussed. The video also delves into calculating wave frequency and period, providing examples and problem-solving exercises to reinforce these concepts.

What do waves primarily transfer?

• Energy

• Light

• Matter

• Heat
