2.  Student will: Wave Properties  Demonstrate Wave Properties

3. A wave is the motion of a disturbance A medium is a physical environment through which a disturbance can travel Waves that require a medium to travel through are Mechanical Waves Electromagnetic Waves such as light do not require a medium to travel

4. A Pulse Wave is a wave that consists of a single traveling pulse A Periodic Wave is when the source of a waves motion is periodic A Transverse Wave is a wave whose particles vibrate perpendicularly to the direction of the wave motion A Longitudinal Wave is a wave whose particles vibrate parallel to the direction of the wave motion

5. There are 3 parts to a wave The Wavelength (λ) is the distance between two adjacent similar points of a wave The Crest which is the highest point above the equilibrium position The Trough which is the lowest point below the equilibrium position A waves Amplitude is the distance from the equilibrium position to the crest

7. Speed of a wave is given by this equation V=fλ Wave speed = frequency x wavelength This applies to both mechanical and electromagnetic waves

8. Example: Wave Magneto is trying to create a magnetic wave to bring down a bridge that the x-men are trying to cross. If the wave he creates has a period of.02 s with a velocity of 150 m/s, what is the wavelength of his magnetic wave?

9. Given: v= 150 m/s T =.02s f = 50 Hz Unknown: λ= ? Steps 1)Define Magneto is trying to create a magnetic wave to bring down a bridge that the x-men are trying to cross. If the wave he creates has a period of 2 s with a velocity of 150 m/s, what is the wavelength of his magnetic wave?

10. Choose an equation or situation: Rearrange the equation to isolate the unknown: 2)Plan

11. Substitute the values into the equation and solve 3)Calculate
