3. Waves

4. Waves are all around us all the time, even if we can’t see them.
Why do we care?
Waves are all around us all the time, even if we can’t see them.
Waves not only explain surfing, but they also explain earthquakes, sound, and one of the most mysterious phenomena on Earth-light

5. What do Waves Do?
Move energy through matter or space

6. Two Types of Waves
Mechanical Waves need matter (medium) to travel through
Electromagnetic Waves can travel through empty space

7. Mechanical Waves water air solids
Mechanical waves travel through mediums such as:
water
air
solids

8. Mechanical Waves
May be longitudinal
Or transverse

9. Types of Mechanical Waves
Transverse Waves – energy moves up and down or side to side while traveling forward
Wavelength
Amplitude
Crest
Trough
How often = Frequency

10. Types of Mechanical Waves
Longitudinal/Compression Waves – energy moves along the medium while traveling forward
Wavelength
How often = Frequency

11. Types of Waves:

12. Mechanical Waves Has wavelength, frequency, and amplitude
Transverse
Longitudinal
Has wavelength, frequency, and amplitude
Energy travels forward but moves up and down/side to side
Has wavelength and frequency
Energy travels forward in pulses

13. Put the following waves under the correct category:
A wave at a ball game
Guitar string
Slinky
Flag waving in the wind
Sound wave
Shaking a rope
Water wave

15. Electromagnetic Waves – Light!

16. Example 1
3 m 2
2 m
3 m
v = f λ
v =1.5 m/s

17. GUESS FORMULA:
G = Givens - write them all down with symbols, numbers and units U = Unknown - write down the unknown with a question mark E = Equation - write down the equation or equations that apply in the problem solve the equation(s) for the desired unknown S = Substitute - substitute the given information into the solved equation S = Solve - solve numerically, paying attention to units identify the final answer by circling, boxing, or underlining it clearly check the final answer to be sure it makes sense
