Electromagnetic Waves and Their Properties

Mr. Anderson explains electromagnetic waves, highlighting their ability to travel through space, unlike sound waves. He discusses the electromagnetic spectrum, detailing the properties of different waves, such as gamma rays and radio waves. The video covers the nature of transverse waves and the role of electric and magnetic fields. It concludes with a comparison of energy transfer methods, emphasizing the unique characteristics of electromagnetic waves.
