The equation of a traveling wave is y= 0.1 sin (200πt-20πx/17), x is in m , y is in mm and t in sec. Find i. The amplitude, wavelength, frequency and the velocity of propagation of wave ii. The equation of wave with double amplitude and double the frequency but traveling exactly in opposite direction iii. The phase difference between a point of 0.25m from origin O and a point 1.10m from O. ​
