Chapter 1 Waves Rev

A disturbance that transfers energy from place to place is called a Wave
Mechanical waves are created when a source of energy causes a medium to Move
The speed of a wave is its wavelength multiplied by its Frequency
The bending of waves around the edge of a barrier is known as Diffraction
The bending of waves due to a change in speed is called Reffraction
The interaction between two waves that meet is called Interfearence
Waves combine to make a wave with larger amplitude in a process called Constructive Interfearence
When an incoming wave combines with a combines with a reflected wave in such a way that the combined wave appears to be standing still,the result is a Standing Wave
What occurs when vibrations traveling through an object match the object's natural frequency? Resanants
A wave travels through a medium because Energy passes from particle to particle
Mechanical waves are classified according to How they move
Frequency is measured in units called Hertz
When a wave hits a surface through which it cannot pass and bounces back,it undergoes Reflection
Waves combine to produce a smaller or zero-amplitude wave in a process called Destructive Interfearence
Why do you see lightning from a distant storm before you hear thunder? Because the speed of light is faster than the speed of sound.
