1. Ch. 14 Waves Concept Review
Milbank High School

2. Parts of a wave
Crest
Wavelength
Amplitude
Origin
Trough

3. Parts of Wave - p.372 Origin - the base line of the energy.
Crest - high point on a wave
Trough - Low point on a wave
Amplitude - distance from origin to crest
Wavelength - distance from crest to crest
Wavelength is abbreviated by the Greek letter lambda = l

4. Transverse Waves SIM
Amplitude SIM

5. Which one of these waves has a larger amplitude?

6. Wavelength Wavelength (λ) λ SIM SIM2 λ
The distance from any point on one wave to that same point on the next wave λ
SIM
SIM2 λ

7. Which one of these waves has a larger wavelength (λ)?

8. Frequency Frequency SIM
The number of waves (or cycles) produced in a given amount of time
SIM

9. Which one of these waves has a higher frequency?

10. Reflection SIM SIM2 Reflection
When a wave bounces back after striking a barrier

11. Diffraction SIM SIM2 Diffraction
The bending of waves around a barrier or through an opening.

12. Sound waves are reflected at a boundary.

13. More Stuff… Points on wave don’t move
What determines how much of a wave is reflected?
