physics required practical 8 waves in a solid

How to find waves in a solid?

• a string is attached to vibrator generator

• there is a mass at the end of a string to keep it taught

• the vibration generator is attached to the signal generator

• signal generator changes the frequency vibration of a string

• when power is turned on the string vibrates forming a wave

Where is the vibrator generator attached to?

to the signal generator

What does the signal generator do?

signal generator changes the frequency and vibration of a string

How does the power affect the string

when power is turned on the string vibrates which creates a wave

How is a standing wave formed?

at a certain frequency by resonance

How to calculate the wave speed of a standing wave?

measure the total length of the wave by using a ruler from the wooden bridge to the vibration generator and then use the wave speed equation

How are half wavelengths are formed?

if the frequency of a standing wave will keep increasing 3 half wavelengths will be formed

How to calculate wave speed of half a wavelength?

divide the total length of the original standing wave by the number of half wavelengths and times by 2

what factors effect wave speed?

mass per cm and taughtness of the string

what factors DON’T affect the wave speed?

length and frequency
