An introduction to the difference between distance traveled and displacement.

Using a one-dimensional number line to visualise and calculate distance and displacement.

When electromagnetic radiation is absorbed by a material the energy it carries has to go somewhere. When lower energy waves, like radio and infrared waves, are absorbed there can be an increase in temperature of the absorbing material. Higher energy waves, like x-ray and gamma waves, can actually permanently damage or change materials. Learn about the different types of electromagnetic waves and how their energies can influence their effects on objects.

Managing time involves accurately predicting how much time it will take to do a task, and then setting aside that amount of time to complete it. Managing time is much more difficult than it may seem, which is why there are entire courses of study and research on the best approaches. But if you develop a method to undertake each component, you’ll be successful.

Using position-time graphs and number lines to find displacement and distance traveled.

This video describes about similar shapes. It can help easily to find size  of a side and angles of similar figures. 

Outcomes

In this course you will learn about:

1. Properties of similar triangles.
2. Conditions for similarity.
3. Proving triangles similar.

An explanation of wave interference and solution of a few examples to find the value of the total wave when two wave pulses overlap

The wavelength and frequency of a wave are related to one another by the speed of travel of the wave, which depends on the type of wave and the medium through which it is passing.

• Make waves with water, sound, and light and see how they are related.
• Discuss wave properties using common vocabulary.
• Explain how changing the frequency and amplitude affects the characteristics of the wave.
• Design an experiment to measure the speed of the wave.
