**The equation of a transverse wave traveling along a very long string is given by y = 6.1 sin(0.010x + 3.0t), where x and y are expressed in centimeters and t is in seconds. Determine the following values.**

(a) the amplitude

6.1

(b) the wavelength

200

(c) the frequency

?

(d) the speed

?cm/s

(e) the direction of propagation of the wave

+x

[-x]

+y

-y

(f) the maximum transverse speed of a particle in the string

cm/s

From the equation i got the amplitude, From the wave # i got the wave length.

K = wave #

K = 2*pi/WaveLength

WaveLength=200

but now i'm stuck on how i'm suppose to find the frequency?

If i could find the period, i could find the frequency. or if i could find the angular frequency I also could find the frequnecy. Once I find frequency, finding speed would be easy. V = WaveLength*frequncey

**How do you know the propagation of the wave? I got it right but it was through guessing.**

-x was the answer.

-x was the answer.

**Also how would i find the max speed? Does it invovle me taking the derivative of the function?**

Thanks!
