Question

The graph between wave number ($\bar{v}$ ) and angular frequency $(\omega )$ is

• A.
• B.
• C.
• D.

Answer 1

Answer: (A)

Wave number, $\bar{v}=\frac{1}{\text{Angular frequency}\left(\omega \right)}$
The graph between wave number $\left(\bar{v}\right)$ and angular frequency ($\omega$) is a straight line which always satisfies the equation $y=mx+c$, where m is slope of the line but not equal to zero. Therefore graph is a straight line as shown in option (a).
