Two progressive waves are travelling towards each other with velocity 50 ~m / s and frequency 200 ~Hz . The distance between two consecutive antinodes is

Options

  1. A0 031 ~m
  2. B0 125 ~m
  3. C0 250 ~m
  4. D0 0625 ~m

Correct answer

B. 0 125 ~m

Step-by-step solution

AS, aligned f &= v [v=50 ~m / s ] &= 50 200 =1 / 4 aligned Now, Distance blw two antinode =1 / 2 array r =1 / 8=0.125 ~m < option-2 array
