Answer electromagnetic radiation moves as electromagnetic waves; therefore, these waves can move through a. both air and space b. only space c. only air

Answer : The correct option is, (a) both air and space

Explanation :

There are two types of waves :

Electromagnetic waves : These are waves which can travel through vacuum. They travel with the speed of light. They does not require a medium to travel.

For Example: Infrared waves, Microwaves

Mechanical waves : These are the waves that require a medium to travel so that they can transport their energy from one location to another.

For Example:  Sound waves

Hence, electromagnetic radiation moves as electromagnetic waves, these waves can move through both air and space.
