A wave equation is given as, $y = cos [300 t - 50 x]$ where y is in mm and x is in m , t is in sec. Choose incorrect statement.

Options:

Answer:

Solution:

Speed $(v) = \frac{ω}{K} = \frac{300}{50} = 6 m / s$ Frequency $= \frac{ω}{2 π} = \frac{300}{2 π} = \frac{150}{π} = 47.7 Hz$ Wavelength $(λ) = \frac{2 π}{K} = \frac{2 π}{50} m = 4 π cm$
