The correct equation of the wave is:
Explanation:The general equation of a traveling wave on a string is given by:
where:
is the amplitude of the wave,
is the wavenumber,
is the angular frequency, and
is the time.Given that the amplitude
, theumber
, and the angular frequency
, we can substitute these values into the general equation to get the specific equation of the wave:
Therefore, the correct equation of the wave is
.
