Solve this following

Question:

Statement-1: Two longitudinal waves given by equations : $\mathrm{y}_{1}(\mathrm{x}, \mathrm{t})=2 \mathrm{a} \sin (\omega \mathrm{t}-\mathrm{kx})$ and $\mathrm{y}_{2}(\mathrm{x}, \mathrm{t})=$ a $\sin (2 \omega t-2 k x)$ will have equal intensity.

Statement-1: Intensity of waves of given frequency in same medium is proportional to square of amplitude only.

 

  1. Statement- 1 is false, statement- 2 is true
