All the options are true for electromagnetic radiation except option (3).
Further explain:
Here, we will see the explanation of each given option.
So, options are explained as.
1. All the electromagnetic radiation travels at the speed of light.
The light wave composed of electric field as well as magnetic field and these fields are perpendicular to each other.
Due to presence of electric field as well as magnetic field in light wave it is known as electromagnetic wave.
So, light is also an electromagnetic radiation.
2. All electromagnetic radiation can be considered as the light.
Yes, all the electromagnetic radiation can be considered as the light, because all the electromagnetic radiation have same property as light but only difference in their frequency and wavelength.
3. All electromagnetic radiation can be seen.
No, all the electromagnetic radiation cannot be seen but some range of electromagnetic radiation can be seen which is known as visible range.
The electromagnetic radiation between this range is generally known as light.
4. All electromagnetic radiation travel in wave.
All the electromagnetic radiation travel is wave form and this wave form is transverse wave.
