This document provides an organizer for a daily lesson on waves. It includes questions of the day about identifying transverse and longitudinal waves. The agenda lists homework assignments and topics to be covered, including worksheets on waves. Jobs are listed for students. Information is provided about the two types of waves - mechanical and electromagnetic. Mechanical waves can travel through matter and include transverse waves, which move energy up/down or side-to-side, and longitudinal waves, which move energy forward in pulses. Examples of different types of mechanical waves are given. Electromagnetic waves can travel through empty space and include light.

3. Waves

4. 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:

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
AmplitudeWavelength
Trough
Crest
How often = Frequency

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

12. Mechanical Waves
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

14. II. Mechanical Waves
Longitudinal Transverse
• Slinky
• Sound wave
• Water wave
• A wave at a ball
game
• Guitar string
• Flag waving in
the wind
• Shaking a rope
• Water wave

15. Electromagnetic Waves – Light!

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
