Question

14 multiple choice 2 points in the diagram, which wave has the largest amplitude? 15 multiple choice 2 points the number of waves passing a point in a unit of time is called frequency wavelength amplitude period

Explanation:

• For question 14: Amplitude is the maximum displacement from the rest position (equilibrium position) of a wave. By visually comparing the waves in the diagram, wave A has the greatest distance from the equilibrium position, so it has the largest amplitude.
• For question 15:
• Frequency is defined as the number of waves passing a point in a unit of time.
• Wavelength is the distance between two consecutive identical points (e.g., crest - to - crest) on a wave.
• Amplitude is the maximum displacement of a wave from its equilibrium position.
• Period is the time taken for one complete wave cycle.

Answer:

1. A
2. frequency
