Awave with a period of three seconds travels at a speed of 12 m/s what is the wavelength of the wave

λ = 0.28m

Explanation:

Equation used is v = λf, where v is velocity, λ is wavelength, and f is frequency

We need to find wavelength so rearrange the equation in term of wavelength.

v = λf

λ = f/v

We know that period is the inverse of frequency (f = 1/T), so lets substitute that into our equation

λ = f/v

λ = (1/T)/v

Plug in your the given values given in the question.

We're given v=12m/s and T=3sec

λ = (1/T)/v

λ = (1/3)/12

λ = 1/36 = 0.2777777 = 0.28m

false

explanation:

boats, things on boats luggage are way more heavy then water.
