Explanation;

• A wave is a transmission of a disturbance from one place, the source to another.
• Waves can be classified as mechanical waves or electromagnetic waves depending on the requirement of a material medium.
• Mechanical waves are those waves that require a material medium for transmission, they include, sound waves, water waves, etc. The transmission of these waves is by vibration of particles in the medium.
• Electromagnetic waves are those waves that do not require a material medium for transmission.They include, radio waves, microwaves, and all the waves in the electromagnetic spectrum.
