Q

What are ultrasound waves?

A

Waves which have a frequency higher
than the upper limit of human hearing

17
Q

Give an example use for ultrasound waves?

A

Medical or industrial imaging.

18
Q

What natural event causes seismic
waves to be produced? What types are
produced?

A

● Earthquakes
● They produce both P-waves and
S-waves

19
Q

State a difference between the mediums that P-waves and S-waves can travel
through

A

P-waves travel through both solids and liquids
● S-waves only travel through solids
(not liquids)

20
Q

What technique is used to detect objects
in deep water and measure water depth?

A

Echo sounding

21
Q

what is echo sounding

A

High frequency sound waves are emitted, reflected and detected
● Time difference between emission and detection,
alongside wave speed, are used to calculate
distances

22
Q

how are sound

A
