A wave on a string is described by the equation y = 0.150 m sin(1.795 x + 2010.6 t).
Two questions:
1. How do I find wave speed?
2. What are the first two times when the vertical position is y = 0.050 m?
Two questions:
1. How do I find wave speed?
velocity = λ * f
My pathway λ → (2pi/λ) = 1.795 ... λ = 3.50m
My pathway f → f = (ω/2pi) ... ω = 2010.6 ... f = 320 Hz
velocity = λ * f ... velocity = (3.50m)*(320Hz) = -1120m/s (Motion→Left)
2. What are the first two times when the vertical position is y = 0.050 m?
Not sure how to go about this...
