PLEASE HELP MEEEEEE
Distance between wave crests, λ
= wave length
= 2 metres
Time complete one wave
= period
= 60 s / 20 waves
= 3 s
Frequency f is number of waves per second
= (1/3) Hz
Speed = f * λ
= (1/3)Hz * 2m
=2/3 m/s
= wave length
= 2 metres
Time complete one wave
= period
= 60 s / 20 waves
= 3 s
Frequency f is number of waves per second

Speed = f * λ
