Period time
Oscillation
Beat
Amplitude
Answer is Right!
Answer is Wrong!
The correct answer is: B. Oscillation.
An oscillation is a repetitive movement that regularly repeats its pattern. One half of a vibration of a body is called an oscillation. For example, if a pendulum swings back and forth, each swing from one side to the other is one oscillation.
The other options are incorrect.
- Period time is the time it takes for an object to complete one oscillation.
- Beat is a periodic variation in the amplitude of a sound wave that is caused by the superposition of two waves of slightly different frequencies.
- Amplitude is the maximum displacement of a vibrating object from its equilibrium position.
