A standing wave is formed by the superposition of two waves travelling in opposite directions. The transverse displacement is given by
What is the speed of the travelling wave moving in the positive x direction ?
(x and t are in meter and second, respectively.)
160 m/s
90 m/s
180 m/s
120 m/s
As discussed in @7297
Speed of the travelling wave in the X direction will be 160 ms-1
Option 1)
160 m/s
This option is correct
Option 2)
90 m/s
This option is incorrect
Option 3)
180 m/s
This option is incorrect
Option 4)
120 m/s
This option is incorrect
