When a vibrating tuning fork is held close to ear?

HomeArticles, FAQWhen a vibrating tuning fork is held close to ear?

When the tuning fork is held close to ear then small amount of air is disturbed and hence sound is faint. When the handle of the vibrating tuning fork is held aganist table it makes the table top to vibrate with forced vibrations.

Q. What is the difference in the vibrations of the tuning fork and the vibrations of the table?

Hitting the fork harder will produce a louder sound because the initial vibration was larger. Touching the vibrating fork to a table after being struck produces a louder sound. When both the table and the tuning fork vibrate, more air molecules are moved than by the tuning fork on its own.

Q. When you keep a tuning fork vibrating close to your ear you hear a faint hum the same fork if you keep it on a table with its stem in contact you hear a loud sound explain?

One hears a faint sound. The same vibrating tuning fork is placed on table, such that its handle is in contact with table, one hears a loud sound. Answer: When the tuning fork is held close to ear, then small amount of air is disturbed and hence sound is faint.

Q. What are the examples of forced vibration?

Forced vibration is when an alternating force or motion is applied to a mechanical system, for example when a washing machine shakes due to an imbalance.

Q. What is the difference between forced vibration and damped vibration?

Answer. Free Vibration: A body oscillates with a constant frequency on its own (without the aid of any external force). Forced vibration: A body oscillates with a constant frequency because of the application of an external force on it. Damped vibration: A body whose amplitude of oscillation decreases over time.

Q. Why is resonance A special case of forced vibration?

Resonance is a special case of forced vibration in which the natural frequency of vibration of the body is the same as the impressed frequency of external periodic force and the amplitude of forced vibration is maximum.

Q. Why is sound louder when a vibration source is held to a sounding board?

Why is sound louder when a vibrating source is held to a sounding board? More surface is forced to vibrate and push more air. Resonance is forced vibration at the natural frequency.
