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
Part A: Transmission and reflection
How do waves reflect off a straight barrier
How do waves reflect off a curved barrier
Straight barrier
Curved barrier
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?
Part C: Diffraction
How does the wavelength affect the diffraction?
How does the opening width affect the diffraction?
Part D: Interference
How does the wavelenth affect the interference pattern?
How does the spacing affect the pattern?
Wave interference
Out
How are waves in 2d the same or different than 1d:
• Transmission
• Reflection
• Refraction
• Interference
