2. In: What one change have you noticed in 2 dimensional waves from one dimension?

3. Objective: To continue to find out about wave properties in 2 dimensions. Success criteria: Understand 2 dimensional: TransmissionTransmission ReflectionReflection RefractionRefraction DiffractionDiffraction InterferenceInterference

4. Ripple Tank Lab Part A: –Transmission and Reflection Part B: –Refraction-from one medium to another Part C: –Diffraction-around barriers Part D: –Interference-constructive and destructive

5. Part A: Transmission and reflection How do waves reflect off a straight barrier How do waves reflect off a curved barrier

6. Straight barrier

7. Curved barrier

8. Part B: Refraction What happens when waves move straight on from less rigid to more rigid media? What happens when they move in at an angle?

11. Part C: Diffraction How does the wavelength affect the diffraction? How does the opening width affect the diffraction?

14. Part D: Interference How does the wavelenth affect the interference pattern? How does the spacing affect the pattern?

15. Wave interference

19. Out How are waves in 2d the same or different than 1d: Transmission Reflection Refraction Interference
