Can someone explain how we perfor sonometer experiment
Answers
Answer:
1) Place the sonometer on table.
2) Make sure that pulley is frictionless.
3) Stretch the wire by placing a suitable maximum load. on.the weight hanger
4) Move the wooden bridges outwards,so that the length of the wire between the bridges is maximum
5) Take a tuning fork of known frequency make it vibrate by striking its prong with a rubber pad,bring it near the ear
6) Compare the sound produced by tuning fork and sonometer wire(sound which has low pitch has less frequency)
7) Gently adjust the bridges for decreasing the length of wire,the sounds appear alike
8) put an inverted v shape paper rider on the middle of the wire.
9)Vibrate the tuning fork and touch the lower end of its handle with sonometer board.the wire vibrates due to resonance and paper rider falls
9) Measure the length of wire between bridges using the meter scale. It is the resonant length and record it in 'length decreasing' column
10)Now bring the bridges closer and then slowly increase the length of the wire till the paper rider falls
11) Measure the length of wire and record it in 'Length increasing column.
12) Repeat the same steps with tuning forks of other frequencies ,and find resonant length each time.
Answer:
Hey Buddy here's ur answer
A tuning folk vibrating with a certain frequency is introduced to the sonometer box and then the length of the string or its tension is adjusted so that the string also vibrates with the same frequency. Since both the systems (tuning folk and the sonometer) vibrate with the same frequency, resonance takes place.
