What apparatus is used to measure waves in a solid?
A string attached to a
vibration
generator
View source
What keeps the string taut in the apparatus?
A hanging
mass
View source
What does the signal generator do?
Changes the
frequency
of vibration of the string
View source
What is a standing wave?
A wave pattern formed by resonance
View source
How do you measure the wavelength of a standing wave?
Measure
total length
from bridge to generator
View source
How do you convert 21.5 centimeters to meters?
0.215
meters
View source
What is the wave equation used to calculate wave speed?
Wave speed =
frequency
×
wavelength
View source
If the frequency is 10 Hertz and the wavelength is 0.215 meters, what is the wave speed?
2.15
meters per second
View source
What happens to the standing wave when the frequency is increased?
It changes to have more
half wavelengths
View source
How do you calculate the wavelength from the total length and number of half wavelengths?
Divide
total length by
half
wavelengths, then
multiply
by
2
View source
What is the calculated wavelength when the total length is 0.215 meters and there are three half wavelengths?
0.143
meters
View source
If the frequency used to create the wave is 15 Hertz, what is the wave speed?
2.15 meters per second
View source
What does the wave speed depend on in the string?
Tautness
of the string and
mass per centimeter
View source
What is the formula to calculate wavelength from total length and half wavelengths?
Wavelength = (
Total length
/
Half wavelengths) ×
2

What are the steps to measure the features of waves in a solid?
Set up the apparatus with a string and mass.
Use a
signal generator
to create vibrations.
Measure the total length of the
standing wave
.
Calculate wave speed using the
wave equation
.
Adjust frequency to observe changes in standing waves.
View source
What are the key concepts related to standing waves in this practical?
Standing waves form due to
resonance
.
Wavelength
is calculated from total length and half wavelengths.
Wave speed is independent of
frequency
and wavelength.
Tautness of the string affects wave speed.
