Required Pratical(Waves in Solid)

What is the Independent variable in this experiment

Frequency of signal generator

What does the hanging mass do

Keeps the string taut

What is the dependent variable in this experiment

Wavelength

What is the control variables

-Same string

-Same masses attached to string

-Same length of string

Describe this experiment

1)Set up apparatus turn on vibrator generator and then adjust frequency of signal generator until solid wave is produced

2)Once standing wave is produced record the frequency of wave shown on signal generator

3)Then measure the the wavelength of the standing wave using a ruler by measuring total length of standing wave from wooden bridge to the vibration generator OR measure multiple wavelengths and divide by number of wavelengths seen

4)Then use wave speed equation which is frequency X wavelength frequency is from signal generator

What does the mass in the experiment help us with

The mass keeps the string taut

What does the signal generator do

Allows us to change the frequency of vibration of the string

How do we calculate the wavelength of three half waves

1)Measure distance from wooden bridge to the vibration generator e.g 0.215m

2)Then divide total length by number of half wavelengths and then X by 2

What does the wave speed of sting depend on

-Taughtness of string

-Mass/cm of string
