Title of Notes: 

Introduction to Waves

the wave, slinky : observations 

Oct 30­2:21 PM

The nature of waves:

What is a wave?A wave is a disturbance or movement that transfers energy from one place to another

‐ Waves can transfer energy over distance without moving matter the entire distance

‐ Forces can start a disturbance

Waves transfer energy NOT matter.  

Oct 30­2:22 PM

The water waves below are carrying energy but are not moving. Waves can only exist as they have energy to carry.

Oct 30­2:24 PM

There are two kinds of waves : 

mechanical waves and 

electromagnetic waves

Today we will focus on mechanical waves

What are mechanical waves?

‐ waves that transfer energy through maer (medium) ‐ A medium is a form of maer through which the wave travels (such as water, air, glass, etc.)  

‐ Examples: (cannot move through empty space)

water waves, sounds waves, waves traveling down a rope or string, earthquake/seismic waves

‐ Empty space: space where no maer is present 

Oct 30­2:54 PM

What are the two kinds of mechanical waves?­ based on how energy moves through them

Transverse Waves type of wave in which the disturbance moves

at right angles (perpendicular) to the direction on which the

wave travels

Longitudinal Waves (Compression Waves)type of wave in which the disturbance moves in the same direction that the

wave travels

Oct 30­3:01 PM

Transverse waves examples

water waves, snapping rope in hand

Oct 30­3:04 PM

Longitudinal waves (compression waves) examples

spring, sound waves
