investigating the variation of the frequency of stationary waves on a string with length, tension and mass per unit length Flashcards
1
Q
what can be investigated?
A
- mass per unit length is constant so
- how frequency depends on length
- how ferquency depends on tension
2
Q
when length is kept constant how is the experimnet done
A
- frequency adjusted so that the wire vibrates at its fundependant frequency
3
Q
How is the equipment set up
A
- calmped at one end, connected to an oscilattor
- other end coneected to pulley wheel with weights on the other end
- connected to signal generator
4
Q
How is mass epr unit length calculated
A
- 2dp balance
- mm ruler
5
Q
How is tension calculated
A
mg
