resonance
Driving at a natural frequency can produce large oscillations. This topic is part of Waves within Science & Nature. This page currently draws on 11 supporting questions, with answers and bonus facts available below.
resonance trivia questions
Resonance occurs when a system is driven near its natural what?
Answer: Frequency
Bonus fact: Driving at a natural frequency can produce large oscillations.
Which musical instrument relies strongly on resonance inside a hollow body?
Answer: Guitar
Bonus fact: The body amplifies string vibrations.
What can happen to vibration amplitude at resonance?
Answer: It can become much larger
Bonus fact: Energy transfer is especially efficient near the natural frequency.
What is the real electronic structure represented by multiple resonance forms called?
Answer: Resonance hybrid
Bonus fact: The resonance hybrid has electron density delocalized across more than one bond or atom.
What feature helps give the sitar its shimmering resonance?
Answer: Sympathetic strings
Bonus fact: Unplayed strings vibrate in response to matching frequencies.
In chemistry, resonance is used when one Lewis structure cannot fully describe what?
Answer: Electron distribution in a molecule or ion
Bonus fact: Resonance structures are alternative drawings of the same arrangement of atoms, not molecules rapidly switching back and forth.
Which ion is commonly shown with several equivalent resonance structures?
Answer: Nitrate ion, NO3−
Bonus fact: The three N-O bonds in nitrate are experimentally equivalent even though a single Lewis structure suggests one double bond.
What acoustic phenomenon occurs when an object vibrates strongly at one of its natural frequencies?
Answer: Resonance
Bonus fact: Resonance can greatly increase vibration amplitude.
Does MRI use ionizing X-rays to create its standard images?
Answer: No
Bonus fact: MRI relies on nuclear magnetic resonance rather than ionizing radiation.
Many Wacom pens can operate without a battery because they use what technology?
Answer: Electromagnetic resonance
Bonus fact: The tablet can power and communicate with the pen through an electromagnetic field.
MRI stands for what?
Answer: Magnetic resonance imaging
Bonus fact: MRI uses strong magnetic fields and radio waves.
