What is the first law of Sonometer?
It is observe that n1l1 = n2l2 = n3l3 =……. = constant, for the constant value of tension (T) and mass per unit length (m). ∴ nl = constant. i.e., n ∝ , if T and m are constant. Thus, the first law of a vibrating string is verified by using a sonometer.
What is the principle of Sonometer?
A Sonometer is a device based on the principle of Resonance. It is used to verify the laws of vibration of stretched string and also to determine the frequency of a tuning fork.
What is Sonometer and example?
A Sonometer is a device for demonstrating the relationship between the frequency of the sound produced by a plucked string, and the tension, length and mass per unit length of the string.
What is Sonometer in physics class 12?
A sonometer is defined as. The device that is used for demonstrating the relationship between the frequency of the sound that is produced by the string when it is plucked and the tension, length, and mass per unit length of the string. The sound is produced in the transverse standing wave in the string.
What is Sonometer used for?
A sonometer is a diagnostic instrument used to measure the tension, frequency or density of vibrations. They are used in medical settings to test both hearing and bone density. In audiology, the device is used to test for hearing loss and other disorders of the ear.
Why is Sonometer called Sonometer?
Answer: Sonometre is made from two words Sono + metre. Sono means sound. Thus sonometre is an device used to measure frequency of sound wave.
Why is it called Sonometer?
sonometer is derived from 2 words – (sono+meter) ; where sono stands for sound. Thus sonometer is an instrument which measure frequency of sound wave. Sonometer is a very simple method for the determination of Frequency of a.c. mains.
Why do Sonometers have two holes?
The holes in the sonometer box provides a way so that vibrations from the tuning fork (which is excited near the sonometer) is transferred to the inside of the sonometer box. Thus, the sonometer box, the bridges and the string are forced to vibrate with the frequency of the tuning fork.
How large is a Sonometer?
What is a Sonometer? Sonometer consists of a hollow rectangular wooden box of more than one meter length, with a hook at one end and a pulley at the other end.
Who invented Sonometer?
The sonomètre is a tuning device invented circa 1694 by Étienne Loulié to facilitate the tuning of stringed instruments. Sébastien de Brossard considered this device to be, “one of the finest inventions,” of the seventeenth century.
Who discovered the Sonometer?
Why does Sonometer box have holes?
