How do waves interact?. Reflection Reflection: Happens when a wave bounces back after hitting a barrier. Reflection: Happens when a wave bounces back.
Waves Energy can be transported by transfer of matter. For example by a thrown object. Energy can also be transported by wave motion without the transfer.

Unit 9 Waves: Diffraction, Refraction, Reflection 02/04/19

Warmup Spring waves travel faster when the tension in the spring is higher/lower (pick one) A sound wave is propagating from left to right below. What direction is the oscillation of a single particle?

Light is a wave and follows wave rules Wave is transport of energy without transport of matter Velocity = wavelength x frequency

Reflection “Change in direction of wave when a wave strikes the boundary of a different medium, resulting in the wave bouncing off the medium.” Example: glare

Diffraction “Spreading of wave around obstacles/slits in its path.” Type of Interference interaction Interference: two or more waves interact and reinforce (+) or cancel each other (-)

Refraction “Bending of wave when it enters different medium where it’s speed is different.”

Cooldown What is the relationship between frequency and wavelength? direct/inverse/quadratic/logarithmic (circle one) Explain your choice Match the words below to their definitions. Draw a picture illustrating each word. Diffraction bending and changing direction of wave Refraction bouncing of wave Reflection bending of wave through/around openings DUE TODAY: LAB, Harmonic Motion (70 max), and Standing Waves (50 max) Work on Wave Actions Worksheet (due Wednesday)
