When a wave pulse is propagating through a medium, displacements of a particle at position ' $x$ ' at time $t = 0$ and $t = 2 s$ are given by $A e^{- 5 x^{2}}$ and $A e^{- 5 x^{2} + 40 x - 80}$ . Speed of pulse in $m / s$ is $____$

Answer:

Solution:

$y = A e^{- (5 x^{2} - 40 x + 80)}$

$= A e^{- 5 (x - 4)^{2}} y = A e^{- b (k x - ω t)^{2}} k = 1, ω = 2, V = \frac{ω}{k} = 2 m / sec$
