1. Waves transfer energy from one place to another with no transfer of mass.

2. Waves can be produced in two ways:

a. Vibration of particles

Tuning fork producing sound waves

Requires a medium for transfer.

Mechanical wave

Examples: sound, water waves, and spring waves

b. Changes in an electromagnetic field

Remote control sending an electromagnetic signal

Small changes in the strength of an electromagnetic field require no medium for transfer.

Electromagnetic wave

Examples: light, microwaves, and X-rays
