Figure shown is a graph, at a certain time \( t \), of the displacement function \( \mathrm{S}(\mathrm{x}, \mathrm{t}) \) of three sound waves 1, 2 and 3 as marked on the curves that travel along \( \mathrm{x} \)-axis through air. If \( \mathrm{P}_{1}, \mathrm{P}_{2} \) and \( \mathrm{P}_{3} \)
P represent their pressure amplitudes respectively, then correct relation between them is :
a. \( \mathrm{P}_{1}\mathrm{P}_{2}\mathrm{P}_{3} \)
b. \( \mathrm{P}_{3}\mathrm{P}_{2}\mathrm{P}_{1} \)
c. \( P_{1}=P_{2}=P_{3} \)
d. \( \mathrm{P}_{2}\mathrm{P}_{2}\mathrm{P}_{1} \)
