Waves

1. Mechanical Waves

   • All types of sound, including music, spoken language, as well as the ocean waves in our scenario are examples of mechanical waves. Mechanical waves must move through medium such as the metal tracks, air or water.

2. Electromagnetic Waves

   • Are light waves, but they don't just include the visible light we can see. Light waves come in all forms depending on how to spread out the wave peaks are. This waves propagate energy forward, but do not use a medium. This is why light can reach Earth from Sun.
