What do waves transfer from one place to another?
Energy
View source
How does light from the Sun travel to Earth?
Through space and the
atmosphere
View source
How does sound travel from a loudspeaker?
By transferring
energy
to
absorbing
objects
View source
What are waves called that move through a substance with particles vibrating at right angles?
Transverse waves
View source
How do particles move in longitudinal waves?
Backwards and forwards in the same
direction
View source
How can transverse waves be created?
By shaking a
rope
up and down
View source
In a transverse wave, how is the oscillation oriented?
At right angles to
energy transfer
View source
What direction do particles move in a transverse wave?
Up and
down
View source
What happens to particles in a transverse wave?
They are not transported along the wave
View source
What types of waves are sound waves classified as?
Longitudinal waves
View source
How can longitudinal waves be created?
By
pushing
a
slinky
forwards and backwards
View source
In a longitudinal wave, how is the vibration oriented?
Parallel to the
direction of energy transfer
View source
What is a compression in a longitudinal wave?
A region of
high pressure
View source
What is a rarefaction in a longitudinal wave?
A region of
low pressure
View source
How is amplitude defined in longitudinal waves?
Maximum distance from
rest position
View source
How is wavelength measured in longitudinal waves?
From center of one
compression
to next
View source
What does frequency measure in waves?
Number of
vibrations
in one
second
View source
What unit is frequency measured in?
Hertz (Hz)
View source
What is the time period of a wave?
Time for one complete
cycle
View source
What are the important terms used to describe waves?
Peak
Trough
Amplitude
Wavelength
Frequency
Time period
View source
How can displacement-distance graphs be used?
To compare
amplitude
and
wavelength
of waves
View source
What does a
displacement-time
graph
demonstrate
?
Displacement of one point on the wave over time
View source
How can displacement-time graphs be used?
To compare the
number of waves
in a time period
View source
What does a shorter time period in a wave indicate?
Higher
frequency
