Mr. Fullerton introduces the characteristics of waves, focusing on transverse and longitudinal waves. He explains key terms like wave speed, wavelength, frequency, and period. The video also covers wave phase, including in-phase and out-of-phase points. Sample questions are provided to reinforce understanding of wave properties, such as amplitude and wavelength, with practical examples.

Which term describes the number of waves that pass a given point in one second?

• Wave speed

• Frequency

• Wavelength

• Period

If two points on consecutive waves are 360° apart, they are said to be:

• Out of phase

• In phase

• 180° out of phase

• 90° out of phase

In a longitudinal wave, areas of very high density are called:

• Troughs

• Rarefactions

• Crests

• Compressions

How is the wavelength of a longitudinal wave measured?

• From crest to crest

• From compression to compression

• From trough to trough

• From baseline to crest
