Reflection on A String
Hard Boundary
Wave reflects on opposite side (opposite phase)
Reflection on A String
Soft Boundary
Wave reflects on same side (same phase)
Refraction on A String
Fast to Slow Boundary
Relation of waves to Incident Wave
Reflected Wave - same speed - same wavelength - opposite phase
Refracted Wave - slower speed - smaller wavelength - same phase
Refraction on A String
Slow to Fast Boundary
Relation of waves to Incident Wave
Reflected Wave - same speed - same wavelength - same phase
Refracted Wave - faster speed - larger wavelength - same phase
Diffraction
The Bending of Waves Around Corners
- Larger Wavelength - greater the angle of diffraction
- Shorter Wavelength - smaller the angle of diffraction
- Also the smaller the gap the greater the angle of diffraction
