Physicslab Sonometer Live Questions
1. What is the principle involved in the Sonometer experiment?
Ans: Resonance
2. What kind of waves are produced in the Sonometer experiment?
Ans: Stationary transverse waves
3. What are transverse waves?
Answer: If the vibrations of the particles are perpendicular to the propagation of the wave, these waves are said to be transverse.
4. What type of transformer is used in the sonometric experiment and what is it?
Ans: Lower the transformer. It is a device that converts high voltage currents to low voltage currents.
5. What is resonance?
Answer: If the applied frequency is equal to the natural frequency of a vibrating body then the body vibrates with the maximum amplitude.
6. Why is the horseshoe magnet used in the sonometric experiment?
7. Why is the ammeter current set to 1amp?
Answer: If you keep more current heat is generated and if we maintain less than 1amp the cable vibrates with less amplitude.
8. What is the use of the rheostat?
Answer: It is a variable resistance.
