FAQs on AC Sonometer Video Lecture - Physics Class 12 - NEET
| 1. What is an AC Sonometer? |  |
Ans. An AC Sonometer is a scientific instrument used to measure the frequency of an alternating current (AC) signal. It consists of a string or wire stretched between two fixed points, with a pulley system at one end and a weight hanger at the other. When an AC signal is passed through the wire, it causes the wire to vibrate, and the frequency of these vibrations can be measured using the AC Sonometer.
| 2. How does an AC Sonometer work? | |
Ans. An AC Sonometer works based on the principle of resonance. When an AC signal is applied to the wire, it creates a standing wave pattern with nodes and antinodes. By adjusting the tension in the wire and the frequency of the AC signal, the wire can be made to vibrate at its resonant frequency. The resonant frequency is the frequency at which the wire vibrates with maximum amplitude. This frequency can be measured using the AC Sonometer.
| 3. What are the applications of an AC Sonometer? | |
Ans. AC Sonometers are primarily used in physics laboratories and educational institutions to study the properties of vibrating strings and the behavior of AC signals. They are commonly used to determine the frequency of AC signals, which is crucial in fields such as electrical engineering, telecommunications, and audio technology. AC Sonometers are also used to investigate the relationship between tension, length, and frequency of vibrating strings.
| 4. How can the frequency of an AC signal be measured using an AC Sonometer? | |
Ans. The frequency of an AC signal can be measured using an AC Sonometer by adjusting the tension in the wire and the frequency of the AC signal until the wire vibrates with maximum amplitude. This is done by changing the weight on the weight hanger and adjusting the frequency of the AC signal generator. Once the resonant frequency is achieved, the frequency can be read directly from the frequency generator or calculated based on the known properties of the wire.
| 5. Can an AC Sonometer be used to measure the frequency of other types of signals? | |
Ans. Yes, an AC Sonometer can be used to measure the frequency of other types of signals, including audio signals and music. By connecting the output of an audio source to the AC Sonometer, the instrument can be used to determine the frequency of the audio signal. This can be particularly useful in music production or sound engineering to analyze the frequencies present in a music track or to tune musical instruments. However, it is important to note that the AC Sonometer is specifically designed for measuring AC signals, and its accuracy may vary when used with other types of signals.
