Exploring Wave Properties and Motion

The video tutorial explores the concept of waves, their characteristics, and examples like light and sound waves. It explains key terms such as crest, trough, wavelength, frequency, and period. The motion of pendulums and their period is discussed, along with graphical representations of waves. The video also covers wave movement types, including longitudinal and transverse waves, and their role in earthquakes. Additionally, it explains spring waves and energy concepts, concluding with resources for further learning.

What type of wave is created by light from the sun?

How is one wavelength measured on a graph?

• From crest to trough

• From origin to the first x-axis intersection

• From peak to equilibrium

• From crest to crest or trough to trough

What does the period of a wave represent?
