📚 In this lesson, you will learn:

How to identify electromagnetic (EM) waves and understand their composition of oscillating electric and magnetic fields.

How to recognise the perpendicular nature of these fields, which oscillate at right angles to each other, classifying EM waves as transverse.

How to distinguish electromagnetic waves from mechanical waves by their ability to travel through a vacuum at the speed of light, 300 million metres per second.

How energy is transferred by electromagnetic waves from a source to an observer, with practical examples like sunlight reaching Earth and radio waves conveying broadcast signals.

✨ Key concepts covered:

Understanding EM Waves: Learn what EM waves are, their oscillating electric and magnetic fields, and their classification as transverse waves.

Speed of Light: Explore the characteristic speed of electromagnetic waves in a vacuum, which is a defining property when compared to other wave types.

Energy Transfer: Discover how EM waves can transfer energy, exemplified by everyday phenomena such as sunlight and radio broadcasts.

By the end of this lesson, you’ll have a comprehensive understanding of electromagnetic waves, what distinguishes them, and how they facilitate energy transfer in numerous aspects of daily life.
