WAVES

WHAT ARE WAVES?

WHAT ARE TWO TYPES OF WAVES?

GIVE EXAMPLES OF BOTH TYPES

WHAT IS REFLECTION, RAREFRACTION, AND DIFFRACTION

• Reflection-light waves bouncing back from a surface
• Refraction-change in the direction of a wave
• Diffraction-bending of a wave around a surface

HOW DO WE CALCULATE THE VELOCITY OF A WAVE?

CONSTRUCTIVE AND DISTRUCTIVE

• Constructive-comes together to make bigger wave
• Destructive-two waves combine to make a smaller wave
