The equation of a simple harmonic progressive wave is given by $y = A \sin (100 π t - 3 x) .$ Find the distance between 2 particles having a phase difference of $\frac{π}{3} .$

Options:

Answer:

Solution:

Given, $y = A \sin (100 π t - 3 x)$

The general equation,

$y = A \sin (ω t - k x)$

$∴ k = 3$

Phase difference, $ϕ = \frac{π}{3}$

$K x = \frac{π}{3}$

$x = \frac{π}{3 k}$

$x = \frac{π}{9}$

Distance, $x = \frac{π}{9} m$
