$$t_0^2 = t_1^2 + t_2^2$$

$$t_0^{ - 2} = t_1^{ - 2} + t_2^{ - 2}$$

$$t_0^{ - 1} = t_1^{ - 1} + t_2^{ - 1}$$

$${t_0} = {t_1} + {t_2}$$

A wave travelling in positive X-direction with a $$=$$ 0.2 ms^$$-$$2, velocity = 360 ms^$$-$$1 and $$\lambda $$ $$=$$ 60 m, then correct expression for the wave is

$$y = 0.2\sin \left[ {2\pi \left( {6t + {x \over {60}}} \right)} \right]$$

$$y = 0.2\sin \left[ {\pi \left( {6t + {x \over {60}}} \right)} \right]$$

$$y = 0.2\sin \left[ {2\pi \left( {6t - {x \over {60}}} \right)} \right]$$

$$y = 0.2\sin \left[ {\pi \left( {6t - {x \over {60}}} \right)} \right]$$
