Wave Diagram, figure out the frequency
Time between first and last wave:
0.02766s-0.00086s=
0.0268s
Waves:
7
Wave period(P):
0.0268/7=
0.0038s
Frequency:
1/P
1/0.0038=
263Hz

What is frequency
Frequency is number of waves passing per second
The unit is Hz
9
New cards
speed formula is
Speed= frequency x wavelength
s= f x λ
