Waves Foldable Directions- Chapter 15
1. Fold four(4) sheets of paper into a foldable with flaps- hamburger style.
2. Number the flaps 1-8 on the left.
3. Label the flaps as follows:
1. WAVES (this is the top flap)- write your name as well
2. Types of waves
Inside flap:
Define : wave, medium, and mechanical wave
Answer questions:
 How does an ocean wave transfer energy across the ocean?
 How are all mechanical waves similar?
3. Transverse waves
Inside flap:
Define a transverse wave
Draw a transverse wave and label the parts: crest, trough, amplitude and wavelength, direction of
disturbance and direction of wave.
Give two examples of a transverse wave.
4. Longitudinal Wave
Inside flap:
Define a longitudinal wave
Draw a longitudinal wave and label the parts:
Compression, direction of disturbance, direction of wave
Give two examples of a longitudinal wave
5. Wave Properties
Inside flap:
Define crest, trough, amplitude, wavelength, frequency
Answer questions:
 What are the properties of a wave that can be measured?
 How is amplitude related to energy?
 How are longitudinal waves measured?
Draw the example wave graph on pg. 499
6. Wave Speed
Inside flap:
Define wave speed,
Write the formula for calculating the speed of a wave.
DO the practice problems on page501 number 1 and 2 as well as the review questions 1-5
7. Wave Interactions
Inside flap:
Define reflection, refraction and diffraction and illustrate an example for each one.
Define interference, constructive interference and destructive interference and illustrate each one.
8. KEY CONCEPTS
Inside flap:
Write the questions and answers to the Chapter review on pg 511-512 numbers 11-34
MAJOR GRADE: Each Flap is worth 10 points=
80
Key Concepts is worth 10 extra points
Neatness10 points
Total=100 points
