13. The period of a wave is 10 seconds and its wavelength is 2 meters. What is the wave's speed?
Before trying to solve for wave speed, there are questions you must answer. Answer the questions below based
on the problem 13. These questions will lead you to answering the problem.
A. Out of the two things you mentioned, which one is given in the problem?
c. Did you notice that you were not given frequency? But you know the period, so you
f
Period
can solve for frequency. Solve for frequency. Use the equation on the right.
d. Now that you know the frequency, using the frequency and wavelength, solve for the wave speed. Use
GUESS
Unknown
Equation
Substitute
Solve
f=
12 m/h
