| Interference: |
|
| A sample problem |

|
|
|
|
| • | When
monochromatic laser light is shone |
||||||||
| on a
pair of double slits, the pattern |
|||||||||
| shown
below is produced on a distant screen. |
|||||||||
| • | What
would happen to the pattern |
||||||||
| if
one of the slits were covered? |
|||||||||
| (Since the interference arises from the
waves from the two |
|||||||||
| slits
interfering with each other, the pattern would go away |
|||||||||
| and
be replaced by an almost uniform brightness.) |
