A plane -progressive wave is represented by the equation. y = 0.1 sin (200nt - 201x /17)
Where y is the displacement in millimeters, t is in seconds and x is the
distance from a fixed origin O in metres (m). Find (i) the frequency of the
wave, (ii) its wavelength, (iii) its speed, (iv) the phase difference in radians
between a point 0.25m from O and a point 1.10m from O, (v) the equation of
a wave with double the amplitude and double the frequency but travelling
exactly in the opposite direction.

Where x and y are in centimeters and t is in seconds. What are
(a) the amplitude
(b) the wavelength

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.

What even is this. where is the question
