Question

A sinusoidal, transverse wave that propagates in the positive x-direction can be described with the wave function y of xt is equal to A times cosine of start parenthesis k times x minus omega times t end parenthesis, where k is the wave number, x is the position of a point on the wave, omega is the angular frequency, and t is time. What is another way to express the angular frequency, omega

Answer 1

Answer:

$\omega =\frac{2 \pi }{T}$ rad/s

Explanation:

The wave function is:

$y(xt) = Acos(kx- \omega t)$

where :

k = wave number

x = position of a point on the wave

$\omega$ = angular frequency

t = time

What is another way to express the angular frequency (omega)

Angular frequency (omega) can be express as :

$\omega =\frac{2 \pi }{T}$ rad/s ( i.e one repetition that it takes to repeats itself)
