Understanding Electromagnetic Waves
Electromagnetic waves are fascinating phenomena that can exist in a vacuum, with electric and magnetic fields oscillating and sustaining each other as they propagate. The concept of fields is abstract, representing values throughout space and time, rather than physical substances. The speed of light applies specifically to these waves in a vacuum, while their speed can be reduced in the presence of matter, affecting their frequency and wavelength.In this clip
