The video tutorial introduces mechanical waves, explaining their types: transverse and longitudinal. It discusses how particle motion relates to energy transfer in these waves. Key characteristics such as period, frequency, amplitude, and wavelength are explored, with examples and calculations to illustrate these concepts. The tutorial concludes with a method to calculate wave speed using wavelength and frequency.

What defines the two types of mechanical waves?

• The medium through which they travel

• The direction of particle motion relative to energy transfer

• The frequency of the waves

• The speed at which they travel

In a transverse wave, how do the particles move?

• Left and right

• Back and forth

• Up and down

• In a circular motion
