1. frequency=40/30 hz

wave velocity= 4.25m/10 sec

frequency*wavelength=wavevelocity
calculate velocity

6. Wavelenth = velocity / frequecy
Frequency=40vibration / 30s=1.33HZ
425cm *100 = 4.25m
Then divide 4.25 m by 10 (the period)
4.35/10 = 0.425 m

7. Wavelenth = velocity / frequecy
Frequency=40vibration / 30s=1.33HZ
425cm *100 = 4.25m
Then divide 4.25 m by 1.33
4.35/1.33= 3.19m then divide by 10
3.19/10 = 0.319
