How to approach it

Predict from the governing principle before looking for a matching option. Then reject alternatives by checking direction, units, limiting behaviour or the physical meaning of each statement.

  1. 1

    Selects option A: the water-wave wavelength is 0.15 m.

  2. 2

    Uses wavelength = wave speed ÷ frequency.

  3. 3

    Calculates 0.60 ÷ 4.0 = 0.15 m.
