The displacement of a wave travelling in the $x$ direction is $y = 1 0^{- 4} sin [600 t - 2 x + π /3] m$ , where $x$ is in metre and $t$ in second. The speed of the wave is

Options:

Answer:

Solution:

Velocity $=$ Wavelength $\times$ Frequency Frequency $(f) = \frac{ω}{2 π} = \frac{600}{2 π}$ Wavelength $(λ) = \frac{2 π}{k} = \frac{2 π}{2} = π$ Velocity $= π \times \frac{600}{2 π} = 300 ms^{- 1}$
