Question

Four sets of waves are given below
(1)$y=a \sin (K x-\omega t)$
(2)$\mathrm{y}=\mathrm{a} \sin (\mathrm{Kx}-\omega \mathrm{t}+\pi)$
(3)$\mathrm{y}=\mathrm{a} \sin \left(\mathrm{Kx}-\omega \mathrm{t}+\frac{\pi}{2}ight)$
(4)$\mathrm{y}=\mathrm{a} \sin (\mathrm{Kx}-\omega \mathrm{t}+2 \pi)$
The two waves which are in phase are\

Two waves are in phase if the phase difference $=0,2 \pi, 2 	imes 2 \pi, 3 	imes 2 \pi-----n 	imes 2 \pi$\
