A woman is standing in the ocean, and she notices that after a wave crest passes by, five more crests pass in a time of 68.0 s. The distance between two successive crests is 34.1 m. What is the wave's (a) period, (b) frequency, (c) wavelength, and (d) speed?

2 answers

  1. 5T=68 => T=68/5=13.6 s
    λ=34.1 m
    v= λ/T
    f=1/T
