New topic – yay! We’ll learn about waves – which is very topical at the moment considering all the earthquakes in Japan. Before we get on to seismic waves we need to have a basic understanding of what a wave is. Here are some of the points we’ll try and answer:-
- What is a wave?
- What is the difference between transverse and longitudinal waves?
- What are some examples of transverse and longitudinal waves?
- What are the amplitude, frequency and wavelength of a wave?
We’ll then take a look at the wave equation v = f λ
This shows us the relationship between speed of a wave v, the time it takes for a particle to vibrate up and down, and the distance between successive waves λ. You’ll need your calculators as we practice solving problems in class.
