Name the two basic types of waves
Transverse
Longitudinal
Is this wave transverse or longitudinal?
Transverse
Is this wave transverse or longitudinal?
Longitudinal
Do ripples on water form a transverse or longitudinal wave?
Transverse
Do sound waves travel as longitudinal or transverse waves?
Longitudinal
Which type of wave oscillates parallel to the direction of travel?
Longitudinal
Which type of wave oscillates
perpendicular
to the direction of travel?
Transverse
What do all waves transfer, and what do they not transfer
They transfer energy,
without transferring matter
What are the regions in a longitudinal wave called?
Compressions
Rarefactions

A
: Crest (or peak)
B
: Trough
C
: Amplitude
D
: Wavelength
What wave quantity is defined as:
"The number of waves passing a point each second"
Frequency
What is the unit of wavelength?
metre
What is the unit of frequency?

Higher tier only
Which type of seismic wave can only travel through solids?
S-wave
Higher tier only
Which type of seismic wave is transverse?
S-wave
Higher tier only
Which type of seismic wave travels at different speeds in solids and liquids?

Describe how ultrasound waves are used to measure distance
A transducer emits ultrasound waves,
these are (partially) reflected from a media boundary
the transducer detects the reflected waves
the total distance travelled is calculated as s = v x t
the distance to the media is
half of the total distance travelled
(as it went there and back)
Higher tier only
What is
echo sounding
used for in water?
Detect objects in deep water and measure water depth.
