2. Do Now Homework Study for test on Wednesday
Complete HW worksheet if you haven’t already
Do Now
Take out Wave HW
Do now will be answered on sheet for the week
Make sure you get the sheet and complete the Do Now for Monday

3. Going over the Do Now A If correct If incorrect
Total at bottom of each day
Correct
Incorrect
Correct
Incorrect A

4. We will have a Mastery quiz on Friday
Same topic as Do Now questions

5. Objectives
SWBAT describe wave interactions by completing frayer models
SWBAT compare and contrast sound and light waves by completing a venn diagram.
Essential Question
How are sound and light waves similar and different?

6. Vocabulary (create for all 4 interactions)
When 2 crests or 2 troughs line up the amplitude increases
When a crest and a trough line up the amplitude decreases
When 2 or more waves interact
to become one wave that is different that the original waves
Interference
Picture
Ripples on a pond to form flat areas and higher peaks
Microwave having “hot spots” and “cold spots”

7. Venn Diagram Sound vs. Light

8. Venn Diagram Sound vs. Light
6 Travels at 300,000 km/s
9 Travels through a vacuum
11Transverse
15 The denser the medium the slower the wave
16Electromagnetic wave
1 Transfers energy from 1 point to another
2 Can reflect
3 Can diffract
4 Can refract
5 Can interfere
8 Travels through a medium
13 Measured in hertz
7 Travels at 346 m/s
10 Longitudinal
12 Measured in decibels
14 The denser the medium the faster the wave
17 Mechanical wave

9. Standing waves and Guitar

10. Answer the Essential Question
How are sound and light waves similar and different?

11. Exit Ticket place the numbers into the Venn Diagram
The denser the medium, the faster the wave
The denser the medium the slower the wave
Travels through air
Can vary in wavelength and frequency
Longitudinal wave
Transverse wave
