Answer 1

electromagnetic waves

Answer 2

Answer;

Electromagnetic waves

Explanation;

• A wave is a transmission of a disturbance from one point to another. It involves movement of energy from the source to another.
• Waves may be classified as mechanical waves or electromagnetic waves depending on whether they require material medium for transmission.
• Electromagnetic waves are those waves that do not necessarily require a material medium for transmission, that is they can be transmitted even in a vacuum. Such waves include, x-rays, radiowaves, microwaves, etc.
• Mechanical waves on the other hand require a material medium for transmission. Such waves include sound waves.
