4.6 Diffraction Flashcards
1
Q
What is diffraction?
A
The spreading of a wave as it foes through an opening or past an obstacle.
2
Q
When is the most diffraction observed?
A
When the opening is significantly smaller than the wavelength.
3
Q
What does the amount of diffraction depend on?
A
The size of the wavelength compared to the size of the aperture of obstacle.
4
Q
When is little diffraction observed?
A
A small wavelength relative to a larger opening or obstacle size.
5
Q
When is appreciable diffraction observed?
A
When the wavelength is comparable to or larger than the opening size.
