Two common types of waves that we will be focusing in this topic are longitudinal and transverse waves.
1. Introduction to understanding the two types of waves mentioned above.
2. Understanding period (T), amplitude (A), frequency (f), wavelength (λ) and speed (v).
3. How can we increase the speed of the wave without changing the medium?
Go to Physics Forum (you can see the link on the right sidebar), and discuss. Then you can attempt to explain how does Tsunami occur and why it is dangerous upon reaching the shores?
