Video 1: Explores what angles are
Video 2: Provides examples of angles
Video 3: Misconceptions about angles

This video explores the angles found in parallel lines.

These three short online lessons discuss asteroids, comets and meteors.

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.

In this course you will learn about:

1. Angles and lines
2. Angles formed between parallel lines.
3. Classifying polygons.
4. Quadrilaterals.

Other objects in the solar system are discussed in this online textbook viz. asteroids, meteorites, comets and dwarf planets.

This video explores the different types of angles that exist.

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.
