Flashcards in diffraction Limit Deck (11):

1

## Wave length of source _____________ forms a diffraction pattern

### Equal to or larger than width of the slit

2

## Path difference of a single slit

###
asin(theta)=m(lambda)

Only forms a diffraction pattern if lambda is greater or equal to a

3

## The greater the number of slits, the ________ the size of the maxima

### Smaller

4

## How do you find the intensity of the slits with different numbers

###
Square the number of slits

Ex. 3 slits, 3^2= 9 x the intensity

5

## How do you determine the number of minimas that are present in a multi slit screen?

###
D-2

Ex: 5 slits are on a screen, 5-2=3 secondary minima

6

## Is rayleighs criterion not resolved, just resolved, or wel resolved?

### Just resolved, where the 1st min overlaps with the primary maxima

7

## ____________ states that the two point resolution limit occurs when the first minimum (the boundary of Airy's disc) of one diffraction pattern coincides with the center maximum of the other diffraction limited pattern

### Rayleigh's criterion

8

## The ability of an optical system to resolve two points or objects

### Resolution

9

## The diffraction pattern formed on a distant screen resulting from a uniformly illuminated circular aperture has a bright region in the center known as ________

### Airy's disk

10

## The central disk plus the surrounding series of concentric bright rings is called the _________

### Airy pattern
