### 17.2Applications of Diffraction, Interference, and Coherence

3.

There is a principle related to resolution that is expressed by this equation.

$θ=λD θ=λD$
17.8

What is that principle stated in full?

4.

A principle related to resolution states, “Two images are just resolved when the center of the diffraction pattern of one is directly over the first minimum of the diffraction pattern of the other.” Write the equation that expresses that principle.

1. $θ=1.22Dλθ=1.22Dλ$
2. $θ=Dλθ=Dλ$
3. $θ=λDθ=λD$
4. $θ=1.22λDθ=1.22λD$
5.

Which statement completes this resolution?
Two images are just resolved when —

1. The center of the diffraction pattern of one image is directly over the central maximum of the diffraction pattern of the other.
2. The center of the diffraction pattern of one image is directly over the central minimum of the diffraction pattern of the other
3. The center of the diffraction pattern of one image is directly over the first minimum of the diffraction pattern of the other
4. The center of the diffraction pattern of one is directly over the first maximum of the diffraction pattern of the other
