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
Selects option A: the water-wave wavelength is 0.15 m.
- 2
Uses wavelength = wave speed ÷ frequency.
- 3
Calculates 0.60 ÷ 4.0 = 0.15 m.
