Sound
|
another form of energy travels in wave form
|
|
|
Transverse
|
(light) wave
|
|
|
Longitudinal
|
Slinky like waves. compression
|
|
|
Sound Waves
|
need a median to travel on
|
|
|
Frequency (f)
|
how often there is reoccurrence; number of waves per second
F = 1/T |
|
|
Wavelength
|
distance travelled by the wave
|
|
|
Speed
|
wavelength x frequency
|
|
|
sound
|
V = wavelength x frequency
|
|
|
Light sound
|
C = wavelength x f
|
|
|
Time Period
|
time taken by one wave
T = 1/f |

|
|
|
Light
|
E = h x f
Energy = planks constant x frequency h = 6.62x10^-34 |
