Question #39386

Two waves 1 and 2 are present on a string:

y1 = ( 35 mm ) Sin[ ( 8.4m^-1 )x - ( 15.7s^-1 )t ]

y2 = ( 35 mm ) Sin[ ( 8.4m^-1 )x- ( 15.7s^-1)t ]

(i) Write the expression for the resultant wave, y = y1 + y2 in the form of wave function

for a standing wave. (ii) Determine the x coordinates of the first two antinodes, starting at

the origin and progressing towards + x direction. (iii) Determine the x coordinate of the

node that is between the antinodes of part (ii).
