    Question

    Wavelength is the length _____.

    1. Of the whole wave
    2. Between two consecutive crests
    3. Between two consecutive troughs
    4. Both 2 and 3

    Hint:

    Distance between two consecutive crests or troughs.

    The correct answer is: Both 2 and 3

      • The distance/length between two consecutive crests or troughs is called wavelength.
      • It is denoted by the symbol Lambda
