1. The problem statement, all variables and given/known data 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. 2. Relevant 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 3. 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!
