Question

What is common to all electromagnetic radiations?

• A. They travel at the same speed in a vacuum (empty space), do not follow laws of reflection and refraction are not deflected by electric and magnetic fields.
• B. They travel at the same speed in a vacuum (empty space), follow laws of reflection and refraction are deflected by electric and magnetic fields.
• C. They travel at the same speed in a vacuum (empty space), follow laws of reflection and refraction are not deflected by electric and magnetic fields.
• D. They travel at the different speeds in all media including vacuum (empty space), follow laws of reflection and refraction are not deflected by electric and magnetic fields.
• E. They travel at the same speed in a vacuum (empty space), do not follow laws of reflection and refraction are deflected by electric and magnetic fields.

Answer 1

The correct option is C

They travel at the same speed in a vacuum (empty space), follow laws of reflection and refraction are not deflected by electric and magnetic fields.

All types of Electromagnetic Radiation:

i) are transverse waves and do not require a medium to travel

ii) travel at the same speed in a vacuum (empty space)

iii) follow laws of reflection and refraction

iv) are not deflected by electric and magnetic fields
