Answer:
[tex]\omega =\frac{2 \pi }{T}[/tex] rad/s
Explanation:
The wave function is:
[tex]y(xt) = Acos(kx- \omega t)[/tex]
where :
k = wave number
x = position of a point on the wave
[tex]\omega[/tex] = angular frequency
t = time
What is another way to express the angular frequency (omega)
Angular frequency (omega) can be express as :
[tex]\omega =\frac{2 \pi }{T}[/tex] rad/s ( i.e one repetition that it takes to repeats itself)
