Flashcards in Intereference Deck (14):

1

## W1=W2

### In phase, bright, traveling same distance

2

## W1 does not = W2=mlambda

### Bright, in phase, one travels longer distance, path difference

3

## W1 does not = W2=(m+1/2)lambda

### Dark, out of phase 180, difference is not one whole wavelength

4

## Condition for bright fringes (constructive interference)

### dsin(theta)=m(lambda)

5

## The condition for dark fringes (destructive interference)

### dsin(theta)=(m+1/2)(lambda)

6

## Condition for interference

### Monochromatic light and mutual coherence

7

## Interference obeys laws of

### Conservation of energy

8

## Borrower the slit distance, the greater

### The angle

9

## For a fixed wavelength, the fringes are wider when...

### The slits are closer together (small d)

10

## Thor a fixed wavelength, the fringes are narrow or finer when

### The slits are farther apart (large d)

11

## For a fixed slit separation (fixed d), the fringes are wider for...

### Longer wavelength

12

## ____fringes are spread out farther than _____ fringes

###
Red

Blue

13

## Fringes for white light illumination

### Interference fringes are colored
