The idea of the electric field, how it's useful, and explains how the electric field is defined.

An image that illustrates light reflecting off a plain mirror.

Forces at a distance are explained by fields (gravitational, electric, and magnetic) permeating space that can transfer energy through space. Magnets or electric currents cause magnetic fields; electric charges or changing magnetic fields cause electric fields.

Magnetism is an interaction that allows certain kinds of objects, which are called ‘magnetic’ objects, to exert forces on each other without physically touching. A magnetic object is surrounded by a magnetic ‘field’ that gets weaker as one moves further away from the object. A second object can feel a magnetic force from the first object because it feels the magnetic field of the first object. The further away the objects are the weaker the magnetic force will be.

Outcomes

By the end of this course you will:

• Be able to define the 'reflection of light'
• Understand the difference between reflected and incident rays
• Be familiar with the two types of reflection viz.: regular and irregular reflection
• Have an understanding of the laws of reflection

This online interactive lesson discusses what reflections are and provides examples of reflections.

This online lesson explains what rotations are.

This video will look at rotation. Rotation involves turning a shape around a set point.

In this lesson you will learn about:

1. Enlargement and reduction of shapes using a scale factor.
2. Reflection of geometric shapes.
3. Translation of geometric shapes.
4. Rotation of geometric shapes.

This online lesson explores the concept of translations.
