Waves

2

What is a wave?

A disturbance that travels through a medium from one location to another location

A medium is a substance or material which carries the wave

3

Longitudinal

Vibrates parallel to (in the same direction of) wave travel

sound waves

the other end of the medium without the actual movement of matter

4

5

Longitudinal

Use your Slinky to demonstrate a longitudinal wave:

Work with a partner
Stretch it out along the table
One of you grasp and draw several coils of a stretched Slinky toward yourself
Release the coils
The other student must hold his or her end of the Slinky still
A longitudinal wave pulse will be generated and travel down the length of the Slinky.

6

Longitudinal

Are composed of

Compressions, where the parts of the medium (coils of the Slinky) are closer together than normal
In this investigation, you created (generated) compressional longitudinal waves
The waves traveled through a media (the slinky)

7

Longitudinal

Use your Slinky to demonstrate a longitudinal wave:

Work with a partner
Stretch it out along the table
One of you stretch a segment of the Slinky
Release the coils
The other student must hold his or her end of the Slinky still
A longitudinal wave pulse will be generated and travel down the length of the Slinky.

8

Longitudinal

Are composed of

Rarefactions, where the parts of the medium are farther apart than normal
In this demonstration, you created (generated) rarefactional longitudinal waves
The waves traveled through a media (the slinky)

9

Transverse

Vibrates perpendicular (at right angles) to the wave travel

Electromagnetic waves

10

Transverse

Use your Slinky to demonstrate a transverse wave:

Work with a partner
One of you move your end of the Slinky back and forth (left and right, like a snake crawling), perpendicular to its stretched length.
The other student must hold his or her end of the Slinky still
A series of transverse waves will be generated and will travel through a medium (Slinky)

11

Water Waves

A combination of longitudinal & transverse

12

Electromagnetic Waves

Wave which is capable of transmitting its energy through a vacuum (i.e., empty space)
Produced by the vibration of electrons within atoms on the Sun's surface
Travel through space until they reach Earth These waves subsequently travel through the vacuum of outer space, subsequently reaching Earth

13

Mechanical Waves

Are not capable of transmitting its energy through a vacuum (space)
Require a medium in order to transport their energy from one location to another

14

Mechanical Waves

Waves traveling through a solid medium can be either transverse waves or longitudinal waves
Waves traveling through a fluid (such as a liquid or a gas) are always longitudinal waves
