Question

The ratio of angular frequency and angular wave number is

• A. particle velocity
• B. wave velocity
• C. energy
• D. wavelength per unit oscillation

Answer 1

The correct option is B wave velocity

Angular frequency = $2\pi f$ and angular wave number = $2\pi /\lambda$
Multiplying each other, we get, $f\lambda =v$, which is the wave velocity
The correct option is (b)
