Resonance Width Hard
Hardphysics
Sharpness of resonance increases when damping:
Select the correct option:
Solution
Incorrect! Answer:
Decreases
The resonance curve (amplitude vs frequency) describes how 'sharp' the resonance is.
- Low Damping: The curve is narrow and tall. This means the system responder strongly only to a very narrow range of frequencies. This is called a high Quality (Q) factor.
- High Damping: The curve is broad and flat. The system responds to a wider range of frequencies but with lower peak amplitude. Therefore, decreasing damping makes the resonance sharper.
