Question

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, 175 m / s, 49 π m / s, 49 / π m s, 0 . 28 π m / s

MARKS App · Accepted Answer

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