|---|---|
| What type of matter does sound travel slowest through? Solid, liquid, gas | gas |

Can you hear a vibration?
These vibrations enter the outer ear and cause the eardrum to vibrate too. We cannot hear the vibrations that are made by waving our hands in the air because they are too slow. The slowest vibration our human ears can hear is 20 times a second. That would be a very low sound.
How does vibration frequency affect the body?
These studies suggested that human biomechanical response, especially for the muscle activity, was significantly affected by frequency of whole-body vibration. Vibration can cause muscle lengthening and shortening, potentially resulting in increased muscle tension due to a stretch reflex [10].
Is it possible to make a sound without causing a vibration?
If the air is an object then no, you can’t produce sound without a vibrating “object”, but if the air is not an “object” then yes you can produce sound without a vibrating object. If an object moves through air faster than the speed of sound, then shock waves in the form of sonic boom is created.
What is free vibration and forced vibration?
Free vibrations are produced when a body is disturbed from its equilibrium position and released. Forced vibrations are produced by an external periodic force. 2. Frequency of free vibrations depends on the body and is called its natural frequency.
What is excitation frequency?
Answer: It is the frequency at which body is made vibrate in forced vibration. It is like complying the body to vibrate the freqency at which the force wants whether then its natural freqency. Importance of it resonace occurs when excitation frequency is equal to natural frequency .
What is excitation?
: excitement especially : the disturbed or altered condition resulting from stimulation of an individual, organ, tissue, or cell.
Is excitation frequency the same as natural frequency?
Harmonic excitation refers to a sinusoidal external force of a certain frequency applied to a system. Resonance occurs when the external excitation has the same frequency as the natural frequency of the system. It leads to large displacements and can cause a system to exceed its elastic range and fail structurally.
