Question

A series of water waves travel 2.8 m in 4.0 s and the distance between successive crests is 1.5 cm. Calculate the frequency at which the waves are being generated.

Please include a detailed and understandable answer for a Grade 11. Thanks :)

Answer 1

f = v / λ, frequency = velocity / wave length

v = 2.8 m / 4.0 sec, v = 0.7 m/sec

λ = 1.5 cm, λ = 0.015 m

Can you substitute and calculate f?
