Question

One end of a slinky was fixed to a wall. Its free end was moved back and forth continuously. What kind of wave does the pattern formed in the slinky represent?

  1. Transverse wave
  2. Longitudinal wave
  3. Both 1 and 2
  4. None of the above

hintHint:

Back and forth movement is present in a longitudinal wave

The correct answer is: Longitudinal wave


    • A wave of motion moves back and forth along the slinky which travels the slinky.
    • It is in the same line as the direction of motion, therefore this is a longitudinal wave.
    • So, the correct option is b.
