Let's do this together!
Wave- a pattern of energy that carries energy from one place to another

• Think like traffic- pulls forward then bunches up.

• Vibrates and travels in the same direction

• Needs a medium to pass through

Longitudinal waves

• Like a snake- moves it's body one way and travels in another.

• Vibrates up and down, but travels forward.

• Light waves

​​Transverse waves

Remember: Both these waves have amplitude
More amplitude = more energy

Hotspot

Which of these areas shows the direction of vibration in a transverse wave?

Which of these areas shows the direction of motion of a transverse wave?

Compressional waves have areas where the molecules are gathered together and other areas where the molecules are expanded.

Comperessional waves go by another name as well- choose the compressional waves in the picture.

Check out the video and write observations about the accordion and how its movement affects the sound.

You cannot view the whole video in the time given, so don't forget to discuss observations on your rooms.

REMINDER- you only have a few words to add here, so discuss a few different ideas with your break-out room!
