![]() 470 © 2015 Pearson Education, Inc.ĩ Chapter 15 Preview Looking Back: Simple Harmonic Motion ![]() ![]() You’ll learn to calculate intensity, a measure of how spread out a wave’s energy is. The lens focuses sunlight into a small area, where the concentrated energy sets the wood on fire. © 2015 Pearson Education, Inc.ħ Chapter 15 Preview Looking Ahead: Energy and IntensityĪll waves carry energy. The terms and equations used to describe waves are closely related to those for oscillations, as you’ll see. The signal is sinusoidal, a form we’ve seen for oscillations. The microphone picks up the vibrating tuning fork’s sound wave. © 2015 Pearson Education, Inc.Ħ Chapter 15 Preview Looking Ahead: Describing Waves You’ll learn the wave model that describes phenomena ranging from light waves to earthquake waves. Shaking one end of the spring up and down causes a disturbance-a wave-to travel along the spring. © 2015 Pearson Education, Inc.ĥ Chapter 15 Preview Looking Ahead: Traveling Waves © 2015 Pearson Education, Inc.Ĭhapter Goal: To learn the basic properties of traveling waves.
