You will be getting a work habits grade today based off of following directions and remaining on task

11. #10-13 Demo then in groups #14-Demo, discuss energy
#15-groups, discuss
A transverse pulse is one in which the motion of the wave is perpendicular (90 degrees) to the motion of the particles of the medium
As the amplitude of a transverse pulse on a spring increases, its speed remains the same
As the frequency of a standing wave increases, the wavelength decreases and the wave velocity remains the same.

18. Physics Talk: Vocab Sheet
Waves Transfer Energy
Example
A wave transfers energy with no transfer of mass
When you throw a ball the mass and kinetic energy move from one place to another
A wave transfers only energy, no mass is moving.

19. Physics Talk: 2 column notes
How is energy transferred?
Chemical energy in musclesmechanical energy in armkinetic energy in spring
Energy transferred from one form to another, but TOTAL energy remains the same…Conservation of Energy!

20. Physics Talk: 2 Column notes
They continue to travel as though the other wave never existed.

What will this look like when the pulses meet?
After that meet?
How do waves “add”?

21. Physics Talk: Vocab Sheet
Periodic Wave
Crest
Trough
Amplitude
Repetitive series of pulses
Highest point on a periodic wave
Lowest point on a periodic wave
Height of crest or depth of trough

22. Physics Talk: 2 Column Notes
How does amplitude relate to sound?
How does amplitude relate to energy?
Large amplitudeLoud sound!
Small amplitudesoft sound
Large amplitudeLarge amount of energy
Small amplitudesmall amount of energy

23. Physics Talk: Vocab Sheet
Wavelength (λ)
Frequency (f)
Distance between two consecutive crests or troughs
Symbol is λ (pronounce lambda)
Number of waves per unit time
Usually waves/sec called hertz (Hz)

24. Wavelength Practice
In the diagram below, what is the wavelength of this standing wave?
12m

25. Physics Talk: Vocab Sheet
Period (T)
Time required to complete one complete wave (crest-trough-crest)
Period and frequency are inversely proportionate
T=1/f
f=1/T

26. Period Practice
What is the period if 8 waves are produced each second?
What is the period if 5 waves are produced in 10 seconds?

27. Physics Talk: Vocab Sheet
Transverse Waves
Compressional (Longitudinal) Wave
The medium moves perpendicular to the direction of the wave
The medium moves parallel to the direction of the wave

28. Physics Talk: Vocab Sheet
Standing Wave
Wave pattern that remains in a constant position.
Does not go right/left, but does go up/down.

29. Physics Talk: 2 Column notes
What type of wave is sound?
Compression Wave
Air molecules get compressed and move through the air

30. Physics Talk: 2 column notes
How can you calculate the speed of a wave?
Speed=Distance/Time
Wave speed=wave frequency x wavelength
