A wave is represented by the equation given by y = 7 sin 7 πt - 0 . 04 πx + π 3 where x is in metres and t is in seconds. The speed of the wave is

speed of wave = coefficient of t coefficient of x ⇒ v = 7 π 0 . 04 π = 175 m / s .

A wave is represented by the equation given by $y = 7 \sin (7 πt - 0.04 πx + \frac{π}{3})$ where $x$ is in metres and $t$ is in seconds. The speed of the wave is

Options:

Answer:

Solution:

$speed of wave = \frac{coefficient of t}{coefficient of x}$

$\Rightarrow v = \frac{7 π}{0.04 π} = 175 m / s$ .
