Homework Statement
A person fishing from a pier observes that four crests pass by in 7.35 s and estimates the distance between two successive crests as 7 m. The timing starts with first crest and ends with fourth crest. What is the speed of the wave?
Homework Equations
f = 1/T
v = f*d
The Attempt at a Solution
T = 7.35s/4 = 1.8375
F = 1/T = 1/1.8375 = .544218
V = .544218 * 7m = 3.81
Can someone tell me what I'm doing wrong? Thanks!
