Question

Speed of sinusoidal transverse wave does not depend upon

• A. time period
• B. frequency
• C. initial phase constant
• D. wave length

Answer 1

The correct option is C initial phase constant

We know that,
Velocity of a sinusoidal transverse wave is,
$v=\frac{\omega }{k}$
Where
$\omega =\frac{2\pi }{T}=2\pi f$ and $k=\frac{2\pi }{\lambda }$
$\therefore v=\frac{\omega }{k}=\frac{\lambda }{T}=\frac{2\pi f}{k}$
$\Rightarrow$ Speed of a sinusoidal transverse wave depend upon time period, frequency and wavelength.
It does not depend on initial phase constant $\left(\varphi \right)$.
