This Guide was prepared for the attached Independent Learning Program (ILP).
Question 1:
To find information on the internet which is easier to understand, and not full of complicated Scientific Jargon, add the words "for kids" to any search you want to complete, for example google search for: "What is a wave for kids?"
Click on this link to watch a 2 minute video explaining the basics of waves:
In your own words, write down what a wave is and how the wavelength and amplitude help to define different waves.
What hypothesis can you make based on the wavelength of any wave, if your not sure ask your teacher.
Include diagrams or photos to explain the different aspects of a wave.
Question 2:
Identified and described means that you need to explain what each of these waves have in common and how they differ to each other.
a) Sound waves are compression waves that can carry information. Read this website to learn more about sound waves write
down at least 5 features of a sound wave.
This video is also helpful in understanding sound waves - don't forget to write down what you learn! what is the speed of sound in air? how does that compare with a jet plane? how far does sound travel in 1 second?
b) Water waves, the video you watched earlier in "basics of waves" showed water waves, did you write down some of the features of water waves? how are they different from sound waves?
c) Light waves, this video is excellent, please watch it. What is the speed of light in air /space? how does that compare with the rockets that went to the moon? how far does light travel in 1 second?
d) Earthquake waves are very different types of waves to those listed above, they can be very destructive. This video explains VERY WELL the difference between 4 types of earth quake waves, make sure you draw some diagrams in your notes explaining each of the wave types. What is the Richter scale and how is it used to measure the strength of Earthquakes?
Question 3:
The Doppler effect can be observed in both sound and light waves. This video is a bit more technical, with some basic Maths and interesting numbers.
Question 4:
The speed of a wave can be calculated using the formula given on this website, check out the example.
Question 5:
