Question

 

Two travelling waves

                      

and                

are superposed on a string. The distance between adjacent nodes is

Solution

Correct option is

 

Distance between adjacent nodes (or antinodes) = λ/2. Also

          = coefficient of x in the argument of the sine function = k

. Hence, the distance between adjacent nodes
