1.) What forms mechanical waves? Unit: Sound and Light Lesson 1: What are Waves? Essential Questions: 1.) What forms mechanical waves? 2.) What are the types of mechanical waves?

What forms mechanical waves? A wave is a disturbance that transfers energy and causes a medium to vibrate.

The material through which a wave travels is called a medium The material through which a wave travels is called a medium. Waves that require a medium to travel through are called mechanical waves.

What are the types of mechanical waves? 1.) Transverse Waves (p.7)

2.) Longitudinal Waves (p.8)

3.) Surface Waves (p.9)
