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.
