In this chapter, we will see how trigonometry is used for finding the heights and distances of various objects, without actually measuring them. 9.2 Heights and Distances

Waves Summary Notes. Waves transfer energy The higher the amplitude the greater the energy of the wave. f=no. of waves produced per second T= time for 1 wave to pass a point. Transverse Wave: The particles of the medium transmitting the wave travel at right angles to the direction of energy travel. e.g. E.M. waves.
Waves: This chapter explores the nature of waves, including types of waves (mechanical and electromagnetic), wave properties, and wave phenomena such as interference and diffraction. Key Features of the Textbook
In summary, \(y(x, t)=A \sin (k x-\omega t+\phi)\) models a wave moving in the positive x-direction and \(y(x, t)=A \sin (k x+\omega t+\phi)\) models a wave moving in the negative x-direction. Equation \ref{16.4} is known as a simple harmonic wave function.
The most familiar type of waves such as waves on a string, water waves, sound waves, seismic waves, etc. is the so-called mechanical waves. These waves require a medium for propagation, they cannot propagate through vacuum. They involve oscillations of constituent particles and depend on the elastic properties of the medium.
