Question

What do radio waves, microwaves, light, and x-rays have in common?

Answer 1

One thing that radio waves, microwaves, light, and x-rays all have in common is that they are all forms of electromagnetic waves.

Answer 2

Microwaves

Light Waves

Radio Waves

X Rays

All above are different energy range of electromagnetic waves

So all of the above have many common properties as following

1. All of the above will travel at speed of
`3 * 10^8 m/s` in vacuum or air

2. All above can travel without any medium as they propagate in form of electric field and magnetic field

3. All waves have effect of medium on their wavelength and speed

4. All waves have no effect on frequency due to change in medium
