which is one characteristic shared by electromagnetic and mechanical waves?\nboth have a frequency and amplitude.\nboth move due to particles bumping into each other.\nboth are formed by charged particles.\nboth occur as a result of a disturbance.
Answer
Brief Explanations:
- Option 1: Both electromagnetic and mechanical waves have frequency (number of oscillations per unit time) and amplitude (maximum displacement from equilibrium).
- Option 2: Mechanical waves move due to particles bumping into each other (require a medium), but electromagnetic waves do not need a medium (they can travel in vacuum).
- Option 3: Electromagnetic waves are formed by charged - particle oscillations, but mechanical waves are not (e.g., sound is a mechanical wave formed by pressure variations in a medium).
- Option 4: While both are related to disturbances (a mechanical wave is a disturbance in a medium, an electromagnetic wave is a disturbance in the electromagnetic field), the more fundamental and shared characteristic in terms of wave - property description is having frequency and amplitude.
Answer:
Both have a frequency and amplitude.
