It does not need a medium to propagate or travel from one place to another. Mechanical waves (like sound waves or water waves), on the other hand, need a medium to travel.
Are there different types of Electromagnetic waves?
Electromagnetic Waves
EM waves are 'transverse' waves. This means that they are measured by their amplitude and wavelength.
Electromagnetic Waves
The highest point of a wave is known as 'crest', whereas the lowest point is known as 'trough'. Electromagnetic waves can be split into a range of frequencies. This is known as the electromagnetic spectrum. Examples of EM waves are radio waves, microwaves, infrared waves, X-rays, gamma rays, etc.
None, ma'am!
Electromagnetic Waves
Are there anymore questions class?
If so, I hope you understood our topic for today
*The bell rings*
Electromagnetic Waves
That concludes this day's lecture. Class dismissed!
