Assertion: The wave function of a pulse is given by

y = \frac{3}{{{{\left( {2x + 3t} \right)}^2} + 4}},

it propagates in

(– \mathrm{ve}) \,x

-direction.
Reason: The given wave function is of the form

y = f(kx +\omega t),

which represent a wave travelling in negative

X

-direction.

View answer and explanation

Correct option: A

If both Assertion & reason are True & the Reason is a correct explanation of the Assertion

Option A is correct because the wave function's form and the sign convention of the argument (kx + ωt) indicate propagation in the negative x-direction.
