Question

Sound travels at 1450m/s through water. If the sound wavesthat travel through the water have a frequency of 180Hzwhat is the length of the sound wave? What is the period ofthe wave?Wave Speed = Frequency * WavelengthFrequency = 1/Period

Answer 1

Step-by-step explanation:

Given:

V = 1 450 m/s

f = 180 Hz

___________

λ - ?

T - ?

The length of the sound wave:

λ = V / f = 1 450 / 180 ≈ 8 m

The period ofthe wave:

T = 1 / f = 1 / 180 ≈ 5.56·10⁻³ s = 5.56 ms
