- Homework Statement
- In the young double-slit experiment I have performed in lab today, I was to point the laser light through the double slits and observe the pattern formed on the screen. An interesting observation I found is that each time when my body come close to the pattern, it gets blurry. It changes from a clear pattern showing individual fringes to a hazy look in which the edges of fringes get blurred out. I tried it couple of times and it happens 6/10 times.
- Relevant Equations
- What might be the possible reasons for this blurry effect? Does the act of human bodies coming near the pattern affect the forming of the pattern?
As I searched online an answer suggested that the blurry effect might be a speckle pattern. However, it still hasn't explained the reason why when my body come near the pattern gets blurry.
