5. Independent Study Learn quiz set 1 -3 Revise for test on topic 1
Due: Fri 26th

6. So waves transfer ENERGY without transferring MASS.
Explore
What are the DIFFERENCES and SIMILARITIES between throwing the ball and talking to you?
“I transfer energy”
“I transfer mass (stuff)”
“I transfer energy too”
“I DON’T transfer mass
(I just make it vibrate)”
So waves transfer ENERGY without transferring MASS.

7. Explore Longitudinal e.g. sound Transverse e.g. light
Vibrations are PARALLEL to wave direction
e.g. sound
Transverse
Vibrations are PERPENDICULAR to wave direction
e.g. light

8. Explain Crest Wavelength Amplitude Trough Higher Frequency
Lower Frequency

9. Explain The speed of a wave is calculated by: Speed = distance time
  v = x t  
Distance must be in m
Time must be in s
Speed will be in m/s

10. Example
If a wave carries a surfer 120m in 60 seconds, what is the speed of the wave?

11. Extend The speed of a wave is ALSO calculated by:
Speed  =  Frequency x  Wavelength
  v = f x λ  
Frequency must be in Hz
Wavelength must be in m.
Speed will be in m/s

12. Extend
A wave has a frequency of 2Hz and a wavelength of 8m, what is its speed?

13. Extend
A wave has a wavelength of 10m, and travels at 50m/s, what is its frequency?
