PhysicsEasysingle choice

A wave pulse is generated in a string that lies along $x$ -axis. At the points $A$ and B, as shown in the figure, if $R_{A}$ and $R_{B}$ are the ratio of wave speed to the particle speed respectively then :

Options:

Answer:

Solution:

$V_{p} = - (V) (slope)$

$\Rightarrow \frac{V_{p}}{V} = - (slope) = \frac{1}{R}$

$\Rightarrow \frac{R_{B}}{R_{A}} = \frac{{(slope)}_{A}}{{(slope)}_{B}}$

as we can see

${(slope)}_{A} > {(slope)}_{B}$

$\Rightarrow R_{B} > R_{A}$
