Group of answer choices

a. a continuous transfer of energy.

b. able to travel through a vacuum.

c. a visible form of energy.

d. able to move particles in a medium.

Answer 1

b. able to travel through a vacuum.

Step-by-step explanation:

The most distinguishing factor of an electromagnetic waves is that they are able to travel through a vacuum.

These waves do not require materials in a medium for propagation.

• Electromagnetic waves are formed by the propagation of the electric and magnetic fields.
• They vibrate at an angle of 90° .
• They are unlike like mechanical waves that requires that requires materials in medium for their propagation.
