Preknowledge: What do you think is the difference between transverse and longitudinal waves?
2. Slide
60 seconds
Longitudinal wave— wave motion is parallel to the particle motion Transverse wave— wave motion is perpendicular to the particle motion (like in water wave)
Transverse vs. Longitudinal waves

Wave: A disturbance that travels through a medium, transferring energy from one place to another
Concepts:
5. Slide
60 seconds
Wavelength: horizontal length from wave peak to peak Frequency : # of waves produced in a given amount of time Amplitude: vertical height of a wave Wave speed: mechanical is determined by the medium in which the wave travels, such as air, water or a solid (except if it is light wave)
Waves Characteristics
6. Slide

Electromagnetic waves—waves that consist of changing electric and magnetic fields that DO NOT require a medium to travel Light is an example of an electromagnetic wave.
What is an EM Wave?
7. Slide
60 seconds
Mechanical Wave - wave causes objects to vibrate Mechanical waves cause medium to vibrate examples: slinky, water, stadium, and jump rope waves
What is a Mechanical Wave?

Which type of wave do 10th graders think is the most interesting?
- Sound waves
- Light waves
- Waves with a combination of both speed and frequency
9. Slide
60 seconds
The speed of waves (if not a light wave) is related to the frequency, meaning the higher the frequency, the shorter the wavelength Waves have different characteristics, such as amplitude, wavelength, and frequency.

How can we measure wave speed and frequency?
13. Slide
60 seconds
Mechanical waves will have increased speed with increased frequency Electromagnetic waves all move at the speed of light: 3 x 10 ^8 meters/ sec Sun is 93 million miles away, light takes 8.3 min to reach Earth
Wave Speed
