The equation for a wave traveling on a string is given by 
, where 
is the distance and 
is the time in SI units. To find the minimum distance between two points having the same oscillating speed, we use the concept that this distance is half the wavelength 
.
To find the wavelength 
:
Here, the wave number 
. Thus,
Thus, the minimum distance between two points having the same speed is:
Distance
