Investigation of the variation of fundamental frequency of a stretched string with length

Label This Diagram

a - paper rider

b - tuning fork

c - string

d - pulley

e - weight

f - bridge

g - sonometer

Demonstrate the method of this experiment • 1

• Place paper rider on string

• Strike tuning fork and place on bridge

Demonstrate the method of this experiment • 2

• Slide bridge until resonance occurs and paper rider falls off

• Strings frequency matches the tuning forks

Demonstrate the method of this experiment • 3

• Measure length between both bridges

• Repeat with other tuning fork frequencies

Define the headings used to graph this experiment

• y - f - Hz

• x - 1/l - m-1

Define a precaution that is associated with this experiment

Keep rider at the centre - where the antinode is
