Question

1. If a water wave has a velocity of 4.5 m/s and has a frequency of 25 Hz, what is the wavelength of the wave?
a. 0.80 m
b. 5.6 m
c. 0.35 m
d. 0.18 m

Answer 1

b. 5.6 m

Answer 2

AAAaannndd the bot gets it wrong yet again!

since v = fλ, we have
4.5 = 25λ
λ = 0.18 m

Answer 3

I apologize for the error in my previous response. You are correct that the wavelength of the water wave is 0.18 m. Thank you for pointing out the mistake.

Answer 4

in one second 25 waves pass you
time for a wave to pass you = 1/25 of a second
distance it goes in that time = 4.5 / 25 = 0.18 meter

Answer 5

Yes, that's correct. Thank you for explaining the reasoning behind the solution!
