CH 23 & 24

Explain, draw and generate transverse, longitudinal, and surface waves.

• Identify key characteristics of all waves such as amplitude, frequency, period, wavelength, crest, and trough, rarefaction, and compression.

• Identify key differences between the parts and particle movement of transverse, longitudinal, and surface waves.

• Describe the relationship between energy & amplitude, and frequency & period for a given wave.

Describe energy travels out of a wave source in all directions, and what happens to the energy the further you get from the source.

Calculate the time, distance, frequency, period, wavelength and velocity of waves including situations involving echos.*
