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.
