Homework Statement
The distance between 10 consecutive crests of transverse waves is 360mm. A crest covers a distance of 40 mm in 2,5 seconds. Calculate the speed, frequency and wavelength of the waves.
Homework Equations
Period: The time taken for one complete vibration
Frequency: The number of complete vibrations per second
S = Speed
D = Distance
T = time
Speed = (distance/time) = (wavelength/period)
V = fλ
λ = wavelength
V= velocity
F = frequency = 1/period
period = 1/frequency
The Attempt at a Solution
f = 40/2,5 = 16
λ = 40 mm = 0,04
v = f * λ
v = 16 * 0,04
= 0,64 m/s
I just want to know if my calculations are correct or I am interchanging the wrong values.
Any help is appreciated, thanks!
