CIE iGCSE Co-Ordinated Science P3.1 General properties of waves Exam Style Questions Paper 1
Question
One property of a water wave is the number of crests on the surface of water that pass a particular point each second.
What is this property?
A. amplitude
B. frequency
C. speed
D. wavelength
▶️ Answer/Explanation
Frequency is defined as the number of complete wave cycles (or crests) that pass a particular point per second. It is measured in hertz (Hz), where 1 Hz = 1 wave per second.
The other wave properties are:
- Amplitude: The maximum displacement of a point on the wave from its equilibrium position (height of the crest).
- Speed: The distance the wave travels per unit time.
- Wavelength: The distance between two consecutive crests or troughs.
Therefore, the property described is frequency.
✅ Answer: (B)
Question
A student investigates the motion of a small ball that is floating on water in a tank. A wave passes along the water surface from left to right.
What happens to the ball?
A. It does not move.
B. It moves only to the left.
C. It moves only to the right.
D. It moves up and down.
▶️ Answer/Explanation
✅ Answer: (D)
Question
What is the name of the distance between one wave crest and the next wave crest?
A. amplitude
B. frequency
C. speed
D. wavelength
▶️ Answer/Explanation
Amplitude is the maximum displacement, frequency is the number of waves per second, and speed is how fast the wave travels.
✅ Answer: (D)
