e. None are correct
Which of the following could be the equation to describe a wave traveling to +x direction that has frequency 50.0 Hz and speed 30.0 m/s wave? a. Y(x,t) = (7.8m)cos [(10.5 m^-1) x ? (314s^-1)] None are correct Y(x,t) = (1.6m)cos [(10.5 m^-1) x ? (314s^-1)] d. Y(x,t) = (0.6m)cos [(1.67 m^-1) x ? (50s^-1)] c. Y(x,t) = (4.2m)cos [(1.67 m^-1) x ? (50s^-1)]b.Explanation / Answer
b is the correct answer because frequency is 50 and speed = 0.6*50 = 30m/s
