Definition of diffraction
Definition of diffraction
Wave spreading in wavefronts through aperture or around edge
Waves encountering obstacles or small openings
Waves encountering obstacles or small openings
Bend and spread out
When diffraction is most pronounced
When diffraction is most pronounced
Wavelength comparable to/larger than opening/obstacle size
Longer wavelengths effect on diffraction
Longer wavelengths effect on diffraction
More diffraction
Narrower slits effect on diffraction
Narrower slits effect on diffraction
More diffraction
Diffraction proportionality relationship
Diffraction proportionality relationship
(wavelength/slit width)
Why light doesn't visibly diffract daily
Why light doesn't visibly diffract daily
Light wavelength very small vs typical openings
Diffraction pattern
Diffraction pattern
Pattern from diffraction and interference combined
Formula for interference minima
Formula for interference minima
Smaller wavelength effect on diffraction angle
Smaller wavelength effect on diffraction angle
Smaller angle to interference minimum
