Write the equation of the wave for a general time t, if the wave speed is v.
According to the question,
At $$t = 0 , g(x) = A \sin (x/a)$$
Wave speed $$= v$$
$$\therefore $$ Time period , $$T = a/v $$ $$(a =$$ wave length $$= \lambda)$$
$$\therefore$$ General equation of wave
$$y = A \sin \{(x/a) - t/(a/v)\}$$
$$= A \sin \{(x - vt) /a\}$$
A travelling harmonic wave is represented by the equation $$ y (x,t)=10^{-3}$$ $$\sin ({50t+2x) , } $$, where x and y are in meter and t is in seconds. Which of the following is a correct statement about the wave? The wave is propagating along the__?
The transverse displacement $$\mathrm{y}(\mathrm{x}, \mathrm{t})$$ of a wave on a string is given by $$\mathrm{y}(\mathrm{x},\mathrm{t})=\mathrm{e}^{-(\mathrm{a}\mathrm{x}^{2}+\mathrm{b}\mathrm{t}^{2}+2\sqrt{\mathrm{a}\mathrm{b}}\mathrm{x}\mathrm{t}\}}$$. This represents a :
