Solution

The correct option is B $y = A sin (v t - k x)$
$(v t - k x)$ is dimensionally in correct because $v t$ is the dimensional of length but $k x$ is dimension less.

Which of the following two wave equations can form stationary wave?

(i) $Y = A s i n (ω t - k x)$

(ii) $Y = A c o s (ω t - k x)$

(iii) $Y = A s i n (ω t + k x)$

(iv) $Y = A c o s (ω t + k x)$

y = A sin (ω t - k x)

y = A sin (ω t + k x)

y = A sin (ω t + k x)

y = A s i n (ω t - k x)

y = a cos (ω t - k x)

x = 0
