I am assigned the even problem for homework, but I am lost, so I found an odd problem with the same type of question and has the answer.... I just need to know how the calculations are done(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

The displacement of a wave traveling in the negative y-direction is D(y,t)=(5.2cm)sin(5.5y+72t), where y is in m and t is in sec. Find the frequency, wavelength and speed of the wave

2. Relevant equations

D(x,t) = A sin[2π (x/λ -t/T) + Φ]

3. The attempt at a solution

I have no clue, the answers are:

11.5 Hz

1.14 m

13.1 m/s
