Question

What are electromagnetic waves? Draw their propagation diagram. Show the electric field amplitude and magnetic field amplitude in the propagation diagram. 
 

Hint:

Electromagnetic waves include all forms of light, radio waves, X-rays, and more, differing only in wavelength and frequency.

Answer 1

- Electromagnetic Waves: Electromagnetic waves are waves that consist of oscillating electric and magnetic fields that are perpendicular to each other and to the direction of propagation. They do not require a medium and can travel through a vacuum. These waves propagate with the speed of light \( c \) in a vacuum and carry energy and momentum. The electric field and magnetic field amplitudes are mutually perpendicular to each other and to the direction of wave propagation. 
 

In the diagram:
- The electric field amplitude (E) oscillates in a plane.
- The magnetic field amplitude (B) oscillates perpendicular to the electric field.
