9.3 Interference of Waves in Two Dimensions
Section 9.3 Questions (p. 460)
-
We have said that waves in a ripple tank are
a "reasonable approximation" to true transverse waves.
- Research the Internet and other sources and report on
how the behaviour of a particle in a water wave does not exhibit
strict transverse wave characteristics.
- When water waves enter very shallow water, for example
as they approach a beach, they not only slow down but also curl
and "break." Explain this behaviour using the information
you obtained in (a).
Water
Waves Main Page
A website that gives information on real and artificial waves. In
particular, look at the section on modelling water waves.
Animations
GIF animations of different wave effects.
Chapter 9 Review (p. 491)
-
Every autumn, some storms off Nova Scotia and
the eastern seaboard of the United States create waves up to 35
m high. Often, rogue waves can appear from the storms hundreds of
kilometres away, so their creation is not just the effect of high
winds. Previous storms have been modelled to help marine forecasters
better predict wave arrivals. Research the Internet for the latest
research on how these waves are created and for the latest improvements
in forecasting techniques. Present your findings in a creative way.

Oceanic and Atmospheric Administration
NOAA warns of dangerous weather, charts our seas and skies, guides
our use and protection of ocean and coastal resources, and conducts
research to improve our understanding and stewardship of the environment
which sustains us all.
Coast
Guard
Actual photos and analysis of the storm that is documented in the
book The Perfect Storm by Sebastian Junger.
Predicting
Hurricanes
A great discussion of how hurricanes form, including satellite shots
and how they help people predict the storms.
